I'm facing problem while importing DWG file in MAX 2008 64 bit.
1. Some faces appears black or either invisible.
2. i use Vray for rendering. when i activate the GI, there are black patches on surfaces which are due to some hidden faces inside surface.(like inside a plane you are having a small plane of random shape) when i look for those faces in CAD i find nothing, surfaces are simple with no inside patches.
please help me....is there anything that should taken cared while exporting from CAD...or any other ways to rectify such problems.
I have gone through your issue. I m working in the field of engineering & scientific visualizations since last 7 Yrs.
I have got enough R&D on these issues to have perfect max geometry from other CAD applications such as Catia, Pro-E, UG, S/W, Rhino, Alibre ect.
I always deal with various CAD formats, u can see some of samples on my online galleries too!
