Hey, well, I''m using 3D Studio Max 5, witht he pada exporter, and everythign is working great. I''m using the CD3DMesh structure for loading my mesh. My textures are not showing up. I checked to ensure it was loading a texture, adn it is, but instead of seeing a box with a texture, I jsut see a gray box. To display my mesh im using mesh->Render(m_pd3dDevice); Here is my code.... 
#define STRICT
#include <tchar.h>
