1) a). Try assigning the default shader to the model, save it and reopen it. Does it still do it?
NO - reassign your texture shader. Save it, reopen it. Does it still do it?NO - Problem Solved.
YES - Open the texture file in Photoshop and resave it as a Targa or IFF. Jpgs are sometimes problematic. Does it still do it?
No - Problem Solved
YES - Skip ahead to b).
YES - Open the texture file in Photoshop and resave it as a Targa or IFF. Jpgs are sometimes problematic. Reassign the textures/shaders. Does it still do it?NO - Problem solved.
YES - Go to step b).
1) b). (Assuming you're working in Polygons) Check to see if the Normals are all pointing correctly. Go to Display > Polygons > Face Normals. They should all be pointing away from the surface. If not, select those faces and go to Normals > Reverse. Does it still do it?
NO - Problem solved.
YES - Delete the problematic faces one by one and redo them using the Append to Polygon tool. Resave it and reopen the scene. Does it still do it?
NO - Problem Solved.
YES - It may be that the file got corrupted. Start over.
2) I'm not into rigging so your guess is as good as mine. NextDesign is right though. It's difficult to diagnose those issues without seeing the scene file.
I hope that is helpful.
