Im using ZBrush for XNA Game Development. I export my models in obj format along with their materials as mtl, but the materials dont work in XNA. It might or might not be because the mtl file only has these lines:
File created by ZBrush
ToolType: PolyMesh3D
www.zbrush.com
newmtl defaultMat
map_Kd SomeBitmap.bmp
How can I solve this?
