Hi everyone.

I have just began my second attempt at a car - the mercedes c class saloon. I have attached a pic of the problem. Theres seems to be a crease near the left side of the light. I always have these problems and would love to know what causes it. Any ideas would be greatly appreciated.

Any other crits or comments are welcome too

Cheers

Could it be becsue there is two verticies there, and they are not welded together? Thats all i can think of :S Could to post a wireframe of it not meshsmoothed?

It's looking good so far though!

hi, thanks for the reply. I have deffinately checked there are not two unwelded points. here is a shot of the unsmoothed model

cheers

Try re-smoothing it... because what happened is the program probably got confused while it was smoothing...

Check which smoothing the groups the two polygons are... and if they are different... make them the same...

Im not the best at this, but Im sure someone can definatly elaborate if that is the problem.

Maybe try to redraw the nearast 4 poly...I think I had the same eproblem before....

Hi guys. thanks for all your suggestions but nothing seems to work. I am using lightwave so I dont think I can change the smoothing groups. Any other ides?

Cheers

this is a big problem with smoothing meshes in lightwave. i have the same problem a lot. apparently there is a way to rotate the two affected poly's and fix the problem but i have not been able to do it yet. it seems to me4 though that the lines of poly's that lead into that crease would end up being quite sharp anyway. put in a headlight, and weld it all up and see whether the crease is still there, it seems to be that whenever a quad poly is stretched a certain distance, it causes major crease problems

it looks like the smoothing is just pulling on the vertices and causing that problem. im not sure how the lines of this car go, but this is the only thing i can think of. i hope it helps!

I dont think it's a good idea sarN..I think a modelled a very similar mercedes (c class)...I think U should chamfer the main line of the hood! (where the hood a bit higher)

let me tell you... as a lightwave modeler.... that you have a nice model there dude... what happens with that little poly pinching won't be seen in the final render... but if you still want to fix it why don't you try to merge the points like this

btw... let me tell you that you have too much polys made ... you might not be able to control all of them at the same time... the secret to get fine and small files is to model it with not too much polys involved to get one smooth or flat shape...

you can see some of my work at www.lwg3d.org :-P (the blue car at the font page was made by me)

Hi guys

thanks for all your suggestions. I particularly liked donchas comment - that the crease wont be seen in the render. A very simple solution lol. thanks also for commenting on my use of too many polys, I always have that problem. I'll try and fix my ways.

I have got bored of that car by this time and am trying to model a ferrari 360 using splines - a new method for me. I'll let you know how it goes and whether I get those damn creases.

Doncha, I also have to say the car in your link is very impressive. Any chance you could post some pics of your C-class for me??

Cheers

Ant

well... it's just that I don't have my pics with me right now... That old blue car was made more than a year ago and remaains into a backup CD somewhere... I've never modeled a Cclass... But i can try ;)

here's the link of the proyect i'm working on rigth now...
