Trials Bike

[-R3D-]

Hey guys, :wave:

Well I am well and truely back into modelling after a long absence.
I've decided to model something from one of my favourite hobbies; A trials bike..

I'm not sure if there are any fellow riders here, but I'm sure some non-riders will like what I've just started.

It's basically a high spec, high strength, light weight bike that you go nuts with over obsticals, walls, fences, rail, you name it.

I'll be modelling the bike in pretty much the same order you'd build the bike up in real life. I will be adding welds to the frame and other relevant places, so it's should come out very life-like hopefully :D

Comments very welcome :-)

Anyway, this is a photo of what I'm modelling:

Sweet, looking very clean.

One suggesting - try to actually connect all the parts, don¨t just let them intersect. It looks bad and drags your model down. Especially at the front part

Edit: Now read the description and saw you are going to do that. That's for posting before reading :wall:

Looking forward for updates!

[ClassicGamer-3DT]

Great start there, are you using booleans? Could run into some problems later on, but so far so good, looking nicely detailed and clean :)

Looking forward to seeing this progress.

Kind Regards,
CG.

[McFly]

Very good start, looking forward to more from you.

[-R3D-]

Zlatovous: Thankyou. I was reading your post and thought to myself "I swear I mentioned the welds" haha :)

ClassicGamer-3DT: I'm using booleans for the CNC machined parts, but cleaning them as I go, so shouldn't have any trouble with a bit of luck.

I will be using hyper nurbs on the parts that warrant it etc..

I've used loft nurbs for the lower thick tube as it shape changing throughout it's length, and sweep nurbs for the other 5 tubes as their profile remains the same throughout their length.

McFly: Cheers, should get some more done today.

[Bob Marley]

Nice so far!!! Did you model this peices with the exact same dimensions as the real one?? So you wont have any bad surprises later on : ) Good Luck

[-R3D-]

Bob Marley: Thanks.. Yes mate, I have the bike right next to me so I can measure thing easily :)



I have actually modelled more of the frame which I'll update in a bit. But for now I just wanted to show you a weld test render.

Used a custom Hi-res displacement map as shown below to get these results..

Regards, Rob.

[I_AM_DAVE_COX]

Nice effect but that isn't how you would weld those seams.

[poopipe]

^^true that

I think the middle of the blobs wants raising up or something - the weld pattern is a bit too sharp
also, I've seen the welds on a zoo frame and they're nowhere near that regular ;)



incidentally, have we met? i used to frequent TF til my knees said no (well, I say frequent - more hang around and make jokes about underage girls)

[StefanC]

Hey,

the bike looks good but I do want to point some things out about the welds, I followed a Metalworker study and got a diploma for it so I worked at companys that work with metal etc... anyway what I am trying to say is is that I know how weld seams look like since I have done it before and yours don't look right :P when welding u add metal to the existing contraption so instead of weld seams looking like it goes inwards is actually supposed to go outwards like a bump, the finger nail shape u did is correct though since thats the effect when molded metal stacks up + the movement u make with the welding torch. also the way u made it the pipes welded is wrong, here is a picture of how it should be and a weld model I did, its not perfect but it should be a bit bumpy and uneven like u see in the pic :

http://img593.imageshack.us/img593/7749/weldexample.jpg

[-R3D-]

Hey all,

Yea I realise the way I "welded" them together isn't correct and it should be the u shape like StefanC FS said. It was only to see the weld "pattern" itself not the weld method. :)

Now, I've taken a closer look at the frame weldings and am currently in the proccess of creating another displacement map to try out.

poopipe: We may have met, not really sure. Erm, only significant thing you'd know me from was when I went to a big meet in 2007 in Southend. Ended up taking a dive off a rail mid move (http://www.youtube.com/watch?v=sL6kjq0k-Y0) lol. But made it when I went back 3 months later (http://www.youtube.com/watch?v=dEOya35yfEY). I was a stock rider back then.

Some photos of the welding on this frame:
(frame is alluminium by the way. I don't know if that makes a difference in the characteristics of the weld)

Will post back soon on the new displacement map.

Regards, Rob.

[I_AM_DAVE_COX]

Are you using nurbs?

[-R3D-]

Yes and no.. Im doing all this in Cinema 4D

Im using sweep and loft nurbs to do the frame tubes. I will be using sweep to make the base mesh for the welds.

I'm using poly modelling & booleans to make the CNC'd parts as C4Ds boolean modifyer is quite clean if used correctly.

I will be using hyper nurbs to model parts that will require it, like the handle bars stem, pedals and tyres etc.


EDIT: New weld. It looks better to me, but then I have been staring at it for ages so I don't know. Turning off AO also helped make the weld seem part of the metal and not just stuck on (See attatchments)


Regards, Rob.

[-R3D-]

Update:

Back to the modelling:

Bash guard mounting points with threads, and the bit the rubber sits in.

Forks will be next to model.

Regards, Rob.

[I_AM_DAVE_COX]

Nice man!

I have to say that you are modelling in an unconventional way but whatever, it works.

[-R3D-]

Update:

Oh and what did yo uthink to my new weld test above; Better that before? :/

Forks done, apart from the welding, which I'll do when I do the frame welding.
http://img207.imageshack.us/img207/6920/56189103.jpg

The headset sealed bearings. And yes that slit is intentional :)

Disc brake mount with thread (May smooth them sharp edges a little come to think of it)
Dropouts (HyperNURBS)

Well, bed time I think...

Nighty night all :wave:

Rob.

[I_AM_DAVE_COX]

Oh yeah I meant to say. the new welds look better but they could be better blended that is all.

I know you said you use lofts and extrudes but I would love to see a quick break-down of how you model some parts.

[-R3D-]

Yea sure. Don't know if these explain anything on my methods, but I've thrown togeather a few screen shots.

They may contain that evil word that noone seems to like :evil: But it's nurbs that don't like playing with booleaned meshes :hurt: so... :)
I never boolean anything that's going to be smoothed with nurbs later.

Coloured parts to show how I made each bit

[I_AM_DAVE_COX]

Very interesting!

I have never seen booleans being used so extensively!

You model in the same way as I model using CAD rather than polygons.

[poopipe]

i vaguely remember that crash I think.

technique wise...
the way i see it is that the frame was probably designed using something like solidworks which is effectively a nurbs/spline modeller so the best tools for the job of recreating it are going to be nurbs/spline based. You could recreate it with subdivs but it'd just take longer and be more effort (much like trying to recreate a mid 90s, nurbs designed car using subdivs)

[-R3D-]

Glad it was informative and gave you some idea of how I'm doing things. I like doing technical things that I have to put some thought into.

Yea I've seen CAD programs; They're beyond me to be honest.

I find it easier to obtain certain shapes using the boolean method if that's how something is in real life (CNC'd). If I tried poly modelling that rear part and nurbs smoothed it, I'd be forever correcting errors.

Yep, I've seen CAD renders on trials forums showing a frame before it's been put through production.

I guess I'm just taking it further by welding it, adding other componants and eventually, doing a final render.

Preview of how welding is coming out:

Still improving my method. Got to go back and redo the forks because it looks too "stuck on" :hurt:

Oh, and a material test. A bit too shiny right now. Needs reducing and blurring.
Sticker has alpha channel problems too. :wall:

[I_AM_DAVE_COX]

Oh yeah I see what you mean!

Still looks nice indeed!

[-R3D-]

Small Update:

Should be able to finish the frame weld tomorrow, hopefully.

Only a clay render; I didn't save the materials and couldn't be faffing around with them again until I need to.

[Bob Marley]

Thats pretty solid man, love the welding keep it up

[I_AM_DAVE_COX]

Yeah that looks epic!

[-R3D-]

Small update from last night, but forum seemed to be down :hmm:

Finished Frame Weld! :dance:

Rob.

[I_AM_DAVE_COX]

Looks very sexy man!

The welding on the V brake bracket looks a bit big though.

[-R3D-]

Another little update...

Stem with allen head bolts and handle bars done :)

Stem: is poly modelled them hyperNURBS smoothed.

Handle Bars: are done with splines in a loftNURBS, in a straight line then shaped with bend deformers

Bolts: are just poly modelled from primitives using bevels and extrudes etc..

I'm really enjoying this project. I'm learning new things and methods all the time :lurve:

I_AM_DAVE_COX: Fixed that weld you mentioned. Found it also went half way up the inside too.. Oh and found that I done the threads the wrong size too :wall: Done M5 instead of M4. Fixed now though.

EDIT: Done few more bits tonight.

Cable clips: Extruded Spline
Stem Top-Cap & Bolt: Poly Modelled then HyperNURBS
Grips: Poly Modelled then HyperNURBS
Bar Ends: Poly Modelled then HyperNURBS

What the hell :crazy:

Thats some sick work, you got there.

[-R3D-]

Thanks guys! :)

Crank arms tomorrow, going to be a tricky shape :xx:

Rob.

[ClassicGamer-3DT]

Oustanding updates, superb mate :)

[jakeydoo]

I like the bike that you have, I built an Onza Woodstock ages ago, it’s a great bike, but I haven’t been out on it lately.
Your progress is really coming along great. Am liking what you have done soo far, and looking forwards to the finished model :D

[MStandar]

I have some questions about your bike (not the model)

What inch is the bike, and what did it cost you when you bought it. The reason for asking those questions is because i have been looking into start biking, but i havnt got the time to start looking into it. what do you believe would be a good bike to start with, around which price tag? Would something like this be worth the money? http://www.tartybikes.co.uk/20_inch_trials_bikes/onza_bird_2010/c10p11226.html

As you probably understands im a total noob when it comes to this kind of stuff, :D

[McFly]

Dude seriously, how far into detailing can you go? Impressive work.

[-R3D-]

Thanks CG & jakeydoo :)

As you probably understands im a total noob when it comes to this kind of stuff, :D

It's classed as Mod, which is 20". For my bike I paid £1405 brand new from tartybikes as a complete custom bike build. I then spent a further £130 on snazzy upgrades like anodized bolts and colour specific parts.

If you want to get into biking, specifically "trials", that bike you linked to is the perfect starter bike. I wanted the old model of the onza t-bird about 10yrs ago but being 15 yrs old back then I never had the money. I used a BMX with a go-kart cog welded to the cranks to lower the gear ratio haha.

The bike you linked to has cable brakes which aren't as powerful as hydraulic ones obviously, but if you are 100% new to trials, you wont need hydraulic brakes for a while, unless you're a very fast learner. Down side with that bike is if you do wish to upgrade to hydraulic on the rear, you can't because it does not have the mounting points to accomodate a hydraulic brake.

The Onza Blade 2010 already has a hydraulic rear brake. The cable front brake can be upgraded to hydraulic in the future for £109 if you wanted to.

Any more questions, feel free to ask... 2 thing I could talk about all day is 3D modelling and trials hehe :D

Dude seriously, how far into detailing can you go? Impressive work.

Oh you haven't seen anything yet ;P

I'm getting so into this detailed modelling, that I've just brought a digital micrometer/Vernier Tool to measure things tons easier than using a bulky plastic ruler :haha:



No update today as I've been getting over a saturday night out (as you do) and I'm part way through making the pedal arm. Which is damn hard I gotta say :xx:

Update tomorrow.. Well, later should I say. It's 5:50am muhaha. Can you tell sunday was a recovery day :D

Rob.

[jakeydoo]

The attention to detail on the BB in insane :D

[-R3D-]

Thought I'd throw this out there ;P

[I_AM_DAVE_COX]

I am pretty sure you should be using CAD software ;)

[MStandar]

Tell me that is a photograph :crazy:

Seriously great work rob

[-R3D-]

You're probably right Dave :) but I haven't any CAD specific programs and I wouldn't know where to start.. But on a good note, I didn't use Booleans on this one (except threads); I poly modelled it from a basic mesh using bevels & cuts etc. Was a tricky shape to achieve, but worth the time I think.

Thanks MStander :) As you can tell, My renders lean towards photorealistic. I'm hoping the final render will be pretty real looking.

[McFly]

Nuts you are my friend. And patient too. And good too. :)

Shader needs a bit more work to be realistic but it's looking great.

[-R3D-]

Cheers McFly :) Yea the shader was just a quicky to test render it. Final materials will be worked on extensively to get as close to the real thing as possible.

[-R3D-]

Another 2 parts:

The ring with the teeth on is smoothed with HyperNURBS, the rest is poly modelled, booleaned etc.

To complete the bottom bracket area; I'll be doing the pedal & crank bolt tomorrow if I'm not feeling too ill. I can feel a cold coming on :(

Rob.

[McFly]

Nice, how many polys so far?

[MStandar]

Whats wrong with you man?
you need to see a doctor soon,, this is way to sick work for a normal person :haha:

Nice updates btw :)

[I_AM_DAVE_COX]

Nice update man!

[karras]

A methodic job, man . 5 Stars for you :wave:

[-R3D-]

Nice, how many polys so far?

So far, just under 309k.. But if I was to colapse all the NURBS modifyers and make everything editable, then I'd have just over 1.2 million polys.

All that renders in less than 3 minutes using the GI with sun method and I'm still getting viewport framerates between 80-110fps


I've done the pedal finally. Such a tricky shape to achieve!! :hurt: But I done it finally.. Will post some clays a bit later when I've done the crank bolts.

[-R3D-]

Here we go. The whole bottom Bracket area done :dance:

Enjoy :)

[poopipe]

I do hope you've reversed the appropriate threads on the BB & pedals :p


it's looking sweet so far - no eno though, boooo!

[-R3D-]

I do hope you've reversed the appropriate threads on the BB & pedals :p


it's looking sweet so far - no eno though, boooo!

I have indeed reversed them where needed :D

Nope, no eno. Just a good 'ol trusty Tensile 60 click :D

[Sathe]

Looking really good man!

[I_AM_DAVE_COX]

Where is the grease at man??!!?

[McFly]

That pedal must have been a bitch to model but you pulled it off nicely. Well done.

[-R3D-]

Thanks Sathe! :)

Where is the grease at man??!!?

Haha, I know I'm modelling all the small details, but come on :D
Sealed bearings anyway, so only grease would be a small amount on the threads before installing :)

That pedal must have been a bitch to model but you pulled it off nicely. Well done.

Thanks McFly. Oh it was a bitch alright! took the best part of the day :ugh:
I was going to use splines and booleans but I wouldn't of achieved the shape 100%. So I started with a cylinder where the writing is. Just boxed the general shape, then started subdividing parts to get the desired shape. There are some tris I couldn't get rid of and some N-gons too, but no way to reduce them to quads or tris without creating bumps etc. C4D handles N-gons quite well when put into a HyperNURBS.

[Tycane3D]

yikes!....thats a lot of detail...good modelling!

Hope once its finished u pay as much attention to its presentation as to its modelling.


Looking great sofar!

[ClassicGamer-3DT]

I really do love you're modelling. Just hope you can do it justice when it comes to texturing and final lighting...... I know that's where I always struggle.

I need to get back into modelling again..... it's been too long.

Great updates so far Rob :)

CG.

[-R3D-]

Why did you stop modelling CG?

[ClassicGamer-3DT]

Don't feel i'm good enough, been wanting to startup again for a while but everything i've tried lately looks awful. I might try something tonight....we'll see.

[McFly]

CG > you're def good enough. You may only lack motivation. Don't know how fast you work but if you feel you're not fast enough, then it's probably a good idea to work on smaller projects to get you going again. Doing so you can finish projects and work faster with every project. You'll then be ready to tackle big $ss projects again! :)

Rob > where at your updates at?

[Mithras]

Amazing work,this is insanely accurate!
Especially love the pedals!

@Classicgamer: Practice makes perfect, idleness doesn't, push some polys :dance:
(and as far as I remember from your Moviemashup entry and other projects your modelling is great)

[-R3D-]

CG mate, I think you're good. I remember you doing the Audi RSQ and I was blown away at the speed you were learning. I wanted to make that car back then, but was only able to do it back in Jan/Feb before I lost motivation and stopped modelling.

As said above, if it is motivation, then something I'd suggest is to make something you really love. That's why I decided to do my bike because I really wanted to get back into modelling. I was out of it from Feb this year to Sept; didn't push a single poly for 7 months :hmm: Now I'm kinda addicted ;P

-------------------------


Just a very small update today. Spent most the day catching up on TV programs and also watched Skyline :drool:

Rear Brake
Clamps & bolts done.
Part of the brake cylinder done.

[Stylus]

Incredible amount of detailing, nice job man.

Keep it up!

[I_AM_DAVE_COX]

I love this!

Just a shame it is not a real bike like a DownHill bike ;)

[-R3D-]

Thanks Stylus!

Not a real bike Dave? :eek: The cheek of it! ;P haha.


Right, I have an update, albeit not anything massive. Just the rear brake, which I think looks pretty cool :cool:

Hope you like

[ZenMan]

Going well so far...try and Update your little "Attachement" image with he best preview of the model. Do this often.

[-R3D-]

Thanks ZenMan!!! Sorted.. Totally forgot about doing that :haha:

[-R3D-]

Front brake caliper finally done! Never again! :ugh:

Rear brake was above and finished.

[I_AM_DAVE_COX]

Great update man!

[-R3D-]

Thanks Dave!

[Zlatovous]

Sweet jesus, great work man. It's shaping up perfectly. No detail left behind :-)

[-R3D-]

Sweet jesus, great work man. It's shaping up perfectly. No detail left behind :-)

Haha cheers mate :) ...Yep, trying to do ALL details where possible.. Very determined to finish it too.

[MStandar]

Yep Rob, I have only one thing to say to you..

SICK WORK man :D

Those calipers, love the details, its gonna look sweet when its textured :)

[Sathe]

If i could rate work on a scale of how heavy I could hit someone this project would be receiving a flying elbow to the neck. :dance:

[-R3D-]

Yep Rob, I have only one thing to say to you..

SICK WORK man :D

Those calipers, love the details, its gonna look sweet when its textured :)

Haha thanks mate! Much appreciated :) You may like the attached render if you're wondering about texturing quality ;)

If i could rate work on a scale of how heavy I could hit someone this project would be receiving a flying elbow to the neck. :dance:

:haha: made me laugh haha :D ...Thankyou, I'm guessing that's the better end of the rating scale then ;P




Below is just a little wip test render I messed around with today briefly. It's my front disc brake rotor.

Rob.

[McFly]

It would be so much easier to just take photos of your bike.

You nuts!

[I_AM_DAVE_COX]

Nice texture work man!

[MStandar]

Are you sure, you didnt photograph youe brake disc? and posted it here.
looks sweet.

[-R3D-]

Honest it's 3D :)

v v v Done this when I was bored last night v v v

[MStandar]

Hehe, Was that one of the easiest parts, it dont look to hard to make, :)

ofcourse i know its 3D, it just looks so real :D

[-R3D-]

Yea was an easy part compared to the front or rear brake..

�•Took a side on photo to get the shape of the disc. (at full zoom to avoid distortion)
•Took some real life measurements and scaled the photo in the 3D world to match those measurements.
•Then effectively traced it; keeping it rotationally symetrical (if that's what it's called) and checked a few measurements to keep it to scale..

It's a big help having a digital micrometer to take measurements. I just round it to the nearest .25mm unless, like the disc, it's a precise part.

:)

[-R3D-]

One Lever down, one to go :xx:

Couldn't be the same could they :haha:

[McFly]

Is the lever actually this sharp? Looks like it can cut.

[-R3D-]

It is that shape, but isn't so sharp it could cut. It's a one finger lever, that's all it needs. A pretty powerful hydraulic braking system :)

[McFly]

Alright! I should get one of those disk brakes cos good ole V-brakes need changing way too often. I use a basic Decathlon Rockrider 5.1 to commute though, so brakes would probably be more expensive than the bike itself. Whatever! Back to modeling man, you got work to do. :)

[-R3D-]

Brake Levers Done!!! :dance:

:xx::xx::xx::xx::xx::xx::xx::xx:

[I_AM_DAVE_COX]

It is really starting to come alive!

[-R3D-]

It is isn't it DAVE.. Getting excited about finishing it now, big time :)

----------------------

Decided to do the rims as they're simple to make, but very nice to look at :drool:

Made a spline cross-section to lathe, then "cut" holes out ;P


Rear wheel is used more than the front, so the rear rim & tyre are wider to spread the riders weight...

It is also an inch smaller in diameter to cater for a tyre with a thicker sidewall. Both tyres have the same out diameter of 20" though. PHOTO OF DIFFERENCE (http://www.biketrialseller.com/upload_file/tires/maxxis_20_tire.jpg)

Had to reposition the rear brake 5mm down the frame as it was off a tad. Was easy enough to do though.

[I_AM_DAVE_COX]

Now that looks awesome but how come the rims are not continuous?

Is it meant to be like that or is it a problem with the sweep?

[-R3D-]

If you're refering to the split in the image with "front rim" & rear rim" written on it, then thats how they are in real life. I think the rims are made from a straight piece bent into a circle, joined internally with 2 rods, then all those holes are CNC'd.

All those holes are to reduce the weight of the rim without sacrificing strength. Plus they look good ;P Real Photo of them (http://www.tartybikes.co.uk/images/custom/echo/large_esl19r.jpg)

The smallest of the holes, the ones facing the center, are for the spokes/spoke nipples. 32 of them per wheel.

[I_AM_DAVE_COX]

Oh I see...thanks for explaining man!

[mohammadyashar]

wow!! man , this is a great job! you make the details so well. I enjoyed it so much.thnx

Right!

I have progress!

And me thinks you will like :)

While I'm rendering off a few angles of my main update, I shall give you this small update to warm you up ;)

Awesome work man!

I miss using c4d haha

[I_AM_DAVE_COX]

God damn man!

[StefanC]

This is eye candy :D

[Matt636]

awesome work.
it might just be the perspective but the wheels look a tiny bit small.
could also be because that the tyres arn't on yet thats making it look weird.

[-R3D-]

Cheers guys :)


Yea it's probably just the lack of tyres Matt.. The bikes modelled to the millimeter :)

Will probably do the tyres on 27th as Im going to my dads shortly for 2 days.

Have a good one guys!

Regards, Rob.

[Tank[NL]]

this just occurred to me: no saddle :)

but damn, you even modelled the welds?

could you post some wireframes? i'd love to see how you did those.

[tillaart36]

his approach on that is on the first or second page ;D

[Tank[NL]]

check

[-R3D-]

Nope, you never sit down in bike trials :)

The welds are a custom displace map applied to a basic mesh that has been made slightly bumpy with noise deformers. As stated by tillaart36 the method is on a previous page, but wires are below anyway for all to see..


Please note everyone. A lot of the model is made up of sweeps, lofts, cleaned up booleans and parts made from edited primitives etc. So that's the reason for the high poly count..

There are very few parts that have been made then smoothed with NURBS. 10-13 parts I think.

Thoses parts being:
Pedal
Handle bar stem
Grips
The 3 cable clips on the left side of the frame
The outsde part of the rear brake
The green bits in the rim (rim tape)
& The 2 cogs..

Images are 1610x1007 direct screen shots.

Enjoy.

[tillaart36]

it all looks great btw i forgot to say :D

hmm I used c4d for a little but couldn't get used to it fast enough so I dropped it...you know any good c4d tutorials on creating hard surface objects with nurbs? Like the things you have on your bike, I would be interested to see.

Keep going!

[MStandar]

Am i on some Hallucinogen or something, because this looks too sweet to be real :D

Thanks for posting man, looks awesome so far :)

[DaddyDoom]

Been following this. Insane work going on dude. Love those wires.
Keep up!

Well Guys... Hope you had a good xmas/holiday etc.... Back to 3D.. :)

Guess who's finished modelling :dance:

Just Textures/Materials now ;P

Enjoy the below eye candy :drool:

[mohammadyashar]

Congratssss!!
heh, hope you have good ones of the things you said !!:D
details are just killing man!! actually looks like a real one.
enjoyed it so much.

[McFly]

Enjoy the below eye candy :drool:

Eye-candy? Where? All I see is your average modeler's work here.

;P

Can't wait to see what beauty renders of this baby look like!

[-R3D-]

Haha :D Thanks guys!!!

[rocneasta]

lovely bike man!

[Denis Ivankovic]

Vey nice bike!
Great model!

[-R3D-]

Cheers! :)

[-R3D-]

Made a start on the frame material as it's used on the biggest parts, frame & forks...

I think it looks about right with the slightly brushed metal look to it..

What you think?

[mohammadyashar]

:shout:COOOL
I prefer mat colors!!

[Matt636]

The tyres was what it needed. good job dude.
I think it would look awesome in mat black.

[isa3dmax]

VahaaHoO:d
great detailing.the render is cool too.

[-R3D-]

Hey guys. Been several days, but done some materials...

Renders straight out of Cinema 4D unedited.

I'm now working with "Linear Workflow" for the first time, so it's taking a little time to adjust my ways to a renderer that doesn't let you cheat to achieve your desired results :xx:

Anyway! To the renders.... Let me know what you think, I'm still tweaking..

The environment isn't final by the way, I just needed something to reflect (It's also from an old project, so not great)

Uhh what a great Modelling. I´ve lost my breath!
Great great i´ve no more words! The detailing is awesome!
Cheers

[MStandar]

That last render, is one of the best ive seen in a long time, This put a big smile on my face :)

[McFly]

Tyre material could do with some tweaking to be more realistic. There's this little I don't know what which yells CG. A little too reflexive maybe?

Welds man, I mean, come on! What were you thinking when you made them?

They look fab, spot on and add so much realism.

On to final renders now!

[I_AM_DAVE_COX]

This is proper man!

Love it!

[-R3D-]

Thanks for the comments guys!

McFly: I wasn't thinking, I just done it :haha: haha.. But I believe the little things that the human eyes usually miss in reality, actually add to the realism in 3D work because your eyes tend to scrutinise what they're seeing :) See bullet point below regarding tyre material.
__________________________________

Added some more textured parts.

Tweaked frame material a little; now happier with it.

•Still feel there's maybe something wrong with tyre material though. I have made the specular lower and wider, it seem a little better.

Also got rid of the visible environment to prevent it drawing your attention away from the model. Left it visible to reflections though.

Next update will be when I've finished or almost finished. These small update are no doubt annoying, and I don't want to keep teasing you all ;P Will update within a week if I get the time to finish it :)

Rob.

I love your WIP, put with this texture...it look like too...perfect

you must add (at lease) some dirt or dust on the tire and the metal 'cause now it look too perfect

continue my friend, its the result will be amazing!!

[Tycane3D]

No missile launchers :(

looks good tho :)

Well, I've finally finish guys!! (I hope) :) Didn't take as long as I thought..

I settled on a studio setup. The wavy noise on the backdrop is intentional and not GI artifacts :)

I hope you like the finished bike and setup, and thanks for all your support during the project, been such a big help!

[Nupsi]

I think that´s the most detailed model I´ve ever seen!! Amazing work, man! Only the rubber material lacks a little of detail, compared to the rest of this masterpiece.

[MStandar]

Sweet work, Those details looks fantastic. have to agree with nupsi, the rubber could use a bit of work, but you can't work on it forever.

[-R3D-]

Thanks guys! :)

Ah, well this is actually what the tyres look like when they're brand new, just plane ol' rubber without much detail except the try-all decal and the sidewall writing and pattern :) Mine isn't as shiny though: SEE (http://www.freewebs.com/huttonbiketrials-20bikes/gu%2020.jpg)

[McFly]

Nice work man, not sure about the brushed metal on the rim (brushes are too wide, don't really know how to explain this) but well done for completing this project.

What's next?

[-R3D-]

Thanks McFly :)

Do you mean the sides of the rear rim that are silver?

[jakeydoo]

WOW I love the end result and have been waiting for this! :D

I have loved the progress from start to end and the shear amount of detail that you have put into EVERY part of each component on this model.

Well done give ya self a pat on the back :D

[McFly]

Thanks McFly :)

Do you mean the sides of the rear rim that are silver?

Yes, like on this render:

http://img521.imageshack.us/img521/5199/87357665.th.jpg (http://img521.imageshack.us/img521/5199/87357665.jpg)
It screams "CG!" when I look at it. ^^ Or is it like that in this real world of ours?

[-R3D-]

Ahhh.. Yea it is.. It's the braking surface around the rim.

In trials you need the best rear brake possible so we run a grinder around the rim to create that rough surface :)

Example (http://www.tartybikes.co.uk/images/custom/large_grind.jpg)

Grinds can vary in looks depending on what width disc you use on the grinder or how hard you push against the rim. So I made mine quite harsh which gives great stopping power :)

[MStandar]

Damn man :D, thanks for showing the photos:

Well now i have to say you got it spot on :D

So are you planing on another project, or are you gonna lay low a while now :)

[The Prime]

I would do some post processing on the images, and add some depth of field to sell the realism more.

[McFly]

R3D > ok I get it now but it's missing a bump map I think. Yeah, I like being picky. :D

[I_AM_DAVE_COX]

Well this was a pleasure to watch!

Agree with McFly about the rear rim. The material needs a little more.

[-R3D-]

I would do some post processing on the images, and add some depth of field to sell the realism more.

Going to play with depth of field in the next renders possibly.

R3D > ok I get it now but it's missing a bump map I think. Yeah, I like being picky. :D

That is the result of a bump map believe it or not :hmm: I think it's because the join between the grind and wheel materials is smooth. Might think about displacement for that one close-up render.

Damn man :D, thanks for showing the photos:

Well now i have to say you got it spot on :D

So are you planing on another project, or are you gonna lay low a while now :)

Thanks :) I haven't thought about what to do next to be honest, I shall have to have a little think about it :)

[mohammadyashar]

I don't understand, I has leaved a comment right after your last renders, but now it isn't there:(
I said , It came out so beautiful , though it was clear at the first. I love It!!

and finally I said, for god please post a matte black painted one. just one shot, for me!!

[Tycane3D]

I think u did great on the modelling, but also think u could push the final presentation a bit harder, I feel it doesn't really do all the hard work and beautifull model justice. :(

I'm just sayin"

[-R3D-]

Right, been tweaking things :)

In 3D:
•Frame material is a little darker to prevent reflections blowing out/over-exposing
•Tyre material is a little darker with reshaped specular to better represent new tyres.
•Pedals are slightly darker with fixed decal, not that they're very visible.
•Reflective values of a few parts have been reduced (pedal arm, front gear, chain, rear brake silver body)
•Tweaked valve material.
•Hadle bars & stem specular value reduced to prevent over-exposure effect.
•Engraved writing on the chain has darker material to give it a little definition on close-up.
•Rear brake line reflective value slightly reduced.
•Rear rim sidewall grind effect achieved with displace map rather than bump map, looks better to me I'd say.
•Reversed front tyre tread pattern because it was backwards.

In Post:
•Brightened & added contrast to the renders using 'levels' in PSP.
•Rendered off depth maps and used PSP to add depth of field to image 4, 5 & 6.

Side Note:
I've decided I'm presenting the bike in this way because I feel adding anything else will distract the eye from the actual model. But it's mostly to stay true-to-life; new trials frames, parts & whole bike builds are presented in this way in real life to best show the build quality, style & details. The very things we all like to see in 3D :)

i've got a question : do you think it's possible to make a stereoscopic render with a DOF in the picture ?
If yes, could you do one render ??? :drool:

Some more Stereoscopic views with depth of field. 2D Version links under each render.

Hello, i have a question - how do you obtain those stereoscopic views?

My second question is - for the welds i saw you mentioned you used sweep nurbs. What did you sweep across what?

[bega]

Outstanding, I followed this from the begning. Can I aask what program you used?

[-R3D-]

Hello, i have a question - how do you obtain those stereoscopic views?

My second question is - for the welds i saw you mentioned you used sweep nurbs. What did you sweep across what?
I rendered the 2 different views/angles in Cinema 4D. Then took the images into Paintshop and split each image into RGB, which results in 3 greyscale images named Red, Green & Blue.

Keep the Red image from the Left eye image, and keep the Green & Blue images from the right eye images.

Then use the "combine RGB channels" function and select the kept greyscale images for each channel. Done! :)

The welds were done using lofts in the end as I had more control over shape and the UVW (Which was important for the weld displacement map to follow the geometry correctly). I used arc'd splines to define the loft shape.

Thanks!.. I used just Cinema 4D R12.

first - amazing renders!
and great work with 3D effect!
How much did you moved the camera between two renders and did both focus on same thing? I try doing it but effect was not so strong as yours... any tips?

[squeak]

incredible work!
sweet modeling

the stereoscopic renders works good too =)

[kazhad]

incredible amount of detail and nice render.
i think i fell in love with your bike :D
perhaps i should go downstairs and pick my big bike and ride it through some mud.

[-R3D-]

Well I just randomly came on threedy and noticed a few replies! Nice to see it getting a few hits once in a while :)

Thought I'd reply because I also have a development.. See the third reply ;)

Thanks!! :)
What I did is duplicate the camera for the other eye, select an object and rotate around that on the horizontal axis only. This object would then be the focal point for the sterioscopic version...

I wouldn't use a defined distance for every render. I'd just done it enough to give a good degree of seperation to give it decent depth.

incredible work!

Thankyou! :)

Hehe, well I fell out of love with it last month and sold her on :(

BUT!! I now have a completely new bike build :dance: (All but the rear wheel, which is out of stock right now)

The new bike is a beaut though, and the only identical objects are;
•Handle bars
•Tyres (thank god!!!!) :haha:
•Grips
•Hubs (Rear hub has a disc mount, which can be copied from front hub)
•Chain
•Freewheel (Front Gear)
•Rear Sprocket/Gear
•Spokes (although they're a different length)
•& Front brake caliper...
•Brake discs are the same design but 160mm instead of 180mm.

The rear brake is now disc too so I can use the front caliper model and modify the mounts slightly.

Other than those parts, everything is wayyyyy different; in shape/design AND colour (no silver this time.. mohammadyashar, you may want to keep an eye out for this one if I start it. It'll satisfy your last request) ;P

So I may just have to dust off the modellers fingers and start chopping the polys again :D (I've not modelled since finishing this project) :hmm:

[kazhad]

hehe. nice. Are you modelling this as well? :D
I just looked over all your renderings and i really like the knit lines!

I've got only a Specialized Enduro Expert with some custom parts. But i definitely need two more bikes. And your thread is one cause for this!!!! xD

[-R3D-]

I think I'm going to start modelling my new bike very soon.. I will start a new thread in the non-organic section when I do start it :) More of those nice welds in a totally different colour :D Clay renders to start off with though, hehe...

Hi Rob,
First your bike model is amazing!
I've been trying to create a weld for about a week now that looks close to yours ( sweep nurbs, loft nurbs) haven't come close. I would be extremely grateful if you could explain your method a little more, or even a screen shot of your object panel maybe? .........thanks for your time,
I learned a lot from your post.........dave

[needse]

@five check this out dude http://cgterminal.com/2011/08/17/3ds-max-welder-1-0-script/

although i dont think this was the method used by R3D

Thanks needse, but thats maxscript....... I have C4D - looks cool tho
