Hello,
I'm importing iges files from Alias Studio ("Surface" to be more precise). Some parts end with poor tesselation.
I've to delete them and re-import (merging) those specific parts in .obj specifying a finer tesselation.
But then the surfaces have different UV mapping coordinates or something like that : the different surfaces of a part have different directions. This appear when using directional shaders (brushed metals). Ugly checker results.
So :
How can I increase the tesselation in a .iges from Alias workflow ?
How can I have good results with brushed metals in .obj parts ?
