Right I Want to improve the render time and quality of the render, I'll post the scene set up, settings of the lighting and what not, the average render time is 25minutes on my DUAL AMD 64bit opteron 250's, 6gig ram, computer so I would of expected it to be faster, So any improvments to that will be great, Also the scene isn't completed as of yet, lots of fine detail still need putting in like lights and what not (How would I make it so a light would come from a modled light? :S the tiled floor did show up because I didn't add it correctly so the next render will have that on :D I will add a picture to the out side when I have it, as its opposite a seaside, should be a nice view.

And heres the Bath room, theres one light coming from the back window, and the only way I've found is to get rid of the noise/black marks is to up the hspehere irratence to about 150, which just takes soo long to render, so any other ways/improvments I can do?

storing the lights with the irradiance map would increase the performance drastically
you could also decrease the hemispheric subdivisions to around 50 ...

Thanks for the reply Vaang, I didnt realise the Hsphere irritation was that high, but thanks for poiting it out, Also I've sdtored the irritance map, but could you explain in detail what it does? :D thanks for the reply.

storing the lights with irradiance map
will blur the shadows but will also considerably speed up your rendering
(but will slower the ir map calculation slightly) as the lights will no longer be calculated separatly from the ir map

So if I stored the irradence maps its good if I want to change a phisical model, but if I wanted to change the settings of the lights/settings I would need to re-calclate the irrdance map again? :S

what you guys think so far? must be a way of making it better? still waiting for the high res picture of the background....

Looking great so far ticktank. I have no idea how to use V-ray but i'm sure some people from this forum will help you... ;0

For thoes that are Intrested (if any) I've got rid of the lights and decided to use HDRI, took me about 4/5 hours to kind of understand it, and then alod of ****** test renders to get not even 50% of the way, but I'm getting there slowy :)
I still need to work on the windoes, there not showing up well/at all and I also want to add caustics (when I find out how) it's still way to dark but I think I'm getting there.
oh the picture I'm using in temporary, I don't acctually have the picture I need, waiting for the client to get it :roll: :roll: so thats why the background looks retarded, its because I'm also using the HDRI for the background to :S Still need to add some dangling lights, and some celling lights to, might do a night and day scene, so one lit up naturaly, and the other using lights at night.
I like the refleciton over the hob, but it stop suddenly, think its becuase I turned off tileing on the HDRI :S silly plonker I am.
ANY SUGGESTIONS WOULD BE VERY APPRICHATED

Ok heres an update: (Can anyone suggest how to make it more realistc?)
I know I need to sort out the burned out areas,
I cant get the ****** main window to show up more, I've got thre reflectiveness up on high!
The picture in the background looks too flat. I think you could try making a semicircular wall to give it a more 3d look. It should work. Your last picture looks cool but it needs less light, just a bit.
I like your work.

the front looks a bit dull maybe you could add awall so the gi can bounce or manually add bounce lights...
your glas looks cool but its missing the typically green border.
If you want you can try the settings from the attached image
just noticed your bath you shouldnt use a sphere shaped light most of the gi rays are going to nowhere better put a plane shaped vraylight (slightly bigger than the window) directly behind the window

Thanks for replies,
SNap007be - Thanks for commecnts, I dont like the background picture either, it's only temporay any how, just there so I can see what the whole picture looks like at the moment, When the client finally gets the picture, I will change it, but I will do the semicircul thing thanks.
Vaang - Thanks for the settings, I've changed them to suit the picture you provided thanks, Altho I won't see the changes till tommorow morning, It basilcy takes 6.5 hours to render, So i leave it on over night, wake up to see what things need to be fixed :) Thats Why I wanna try my best everynight before I render.

I dont know if you guys can help me tho, I havnt used this thing before but I'm sure this is the thing I need, it's the Mask tool, Now I want to put a decal on the cooker, So I've got it all set up on the cooker with the uvw maps, Now I just want to make it so only the black lines/numbers show up and the rest is invisible for the chrome to come through.... see the shots below?: (the red is just 2 spheres so I know if the chrome is showing (all that white background hard to make out))
can anyone give a hand? :)

Hey ThinkTank, I have the worst time trying to get Vray to work well. I either get way too dark, or (usually) way too washed out bright...Even when I use vray maps. I tried like 3 different tuts but the settings have to be so different each scene i do, so I'm not learning the best method for lighting...I tried both planar and sphere vray lights with the same results...
I'm sure the way you're doing it is the right way...I just use transparancy maps to get logos and such to come through...
23-12-2004, 04:33 AM
I would suggest to learn Global Illumination first, master that (theres lots of settings to play with,) and then go on to V-ray Lights, V-ray lights also work on distance as well as energy, so beware :)
23-12-2004, 04:34 AM
you could try a composite map with vraymaterial at layer 1 and the decal at layer 2
23-12-2004, 04:37 AM
Would you explain a bit for me :-) I take a while to understand things :)
23-12-2004, 04:45 AM
i´m not good in expalining things with words ^^
23-12-2004, 04:53 AM
Thats lovly, thanks for that, I really need the image!! Now I understand :D:D:D
23-12-2004, 05:04 AM
easier way: just copy the maskbitmap from your first material to reflection ... that should work too
23-12-2004, 04:21 PM
Heres an update, I had to removed the blinds because client didn't want them (also the glass was special so it was hard to see through when the lights are out).
I've also got problems with the Anti Alising, Can anyone suggest a good screen shot of a good set of settings for a final render for anitanilising?
Also I've notcied that the renders are showing the "buckets" like differnt shades were the buckets were and it isn't blended in with the rest of the image, its werid!?!?!?!?
