Unwrap and subdivision !!!

[BattlemasterXP]

It's a common and known issue of 3Ds Max.

You can reduce those distortions by adding additional loops -in your case in the horizontal
level. It's a real problem when you have more organic like objects, like cars etc, where you can't add loops without creating bumps or shape modifications.
You could also unwrap your smoothed mesh, but this will creat laggs when you have more complex shapes/ more polygons.

You should search the forum for UVW distortion or Turbosmooth UVW.
There is a huge diskussion thread.

thx a lot for ur replay :)
it is not good thing to change the wireframe lines on complix models as u said
also unwraping model after subdivision is very hard and will make problems with some polygons
u mean that this problem is in 3ds max only ? ... maya or softimage have the same prob or not ?

Try the search function, easy too use, doesn't hurt and you might stumble upon this one. (http://forums.cgsociety.org/showthread.php?f=6&t=453214&page=4&pp=15).

also unwraping model after subdivision is very hard and will make problems with some polygonsActually it's not when ypou do it on an unsmoothed object before. Sounds like double work, but in most cases distortions can be removed kinda quick using the relax tool in the unwrap editor.

Well, I don't know if Maya has similar problems, though,
but I know that Softimage XSI can deal with those uvw coordinates much smoother
and in the end better.

Back to the smoothed unwrapping:
As scrimski explained (you have to unwrap your lowpoly object first,
smooth it and then add another uvw modifier to your stack.
Sorry that my post was ambiguous.

It kinda double work when you have to do LOD for your models,
but there are also solutions without unwrapping your whole model again,then.

Good luck!
