Hey guys,

I've been working on a model and I am doing the normal mapping tests and I have come across a problem. Mind you this is my first time doing this so bare with me. Below is the image. The program I a using is 3ds Max 9 (not 2009).

The projection cage is not crashing into the high-res geometry, and that is not the only place that it is occurring. The high-res model in this test is intermediate detail from MudBox and not the full detail model. My question is whats happening ? And is there a way to fix it? Any suggestions would be much appreciated. Thanks to those that reply.

hi
check these,
1 use normal modifier (unify normals),
2 check for polygon crossing (polygons that weld wrongly or two polygon cover each other).
3 export model with various formats this and open it again this almost shows the problem because errors export wrongly and in import show themselves.
