Character or asset appears black
From HEWIKI
If your character or asset appears black
- There is painted vertex data that has gone bad. This is a common problem with 3ds Max losing track of vertex paint color channel information thus leaving the model all 'black'. Sometimes a 3ds Max mesh can become corrupted when moving between different versions or through other formats such as FBX. It makes it hard to spot since Max doesn't make it easy to view the vertex paint. To test if this is a problem, try vertex painting the model white and re-exporting.
- If all else fails try resetting the XForm.
