distorted render result with vray glasmaterial

[maxs]

i have a problem by changing the glasmaterial of this cars(dosch 3d cars 2006) to a vray material. aim is to delete all raytrace materilas, worked perfect out of the windows of the cars. the first car has a vray glasmaterial in the windows and shows a distorted result, the other cars have a max material in the windows which do not occure that effect.

would be also thankfull for suggestiions where to find realistic 3d car geometry with vray materials.

I think it's because the glass has no thickness. Either give thickness (shell modifier in max) or reduce to ior of the glass down to somewhere around 1.02 (not realistic.)

[max.m]

thx ray, works perfect with shell modifier.
