I have created a scene with many textures and when viewing in the main window with hardware texturing active shows some objects with a black/white 'cross hatching'.
These are using a texture map that's used elswhere in the scene without problem.
The frame renders OK, it's just annoying to see all but these objects textured correctly.
I've played around with the face and vertex normals to no effect.
My graphics card is an nvidia fx3700 supported by autodesk.
