player went white

When I upgrade 3dgs from 7.07 to 7.7, my player turn white! I didn't use any shader on it and changing models doesn't work.It works perfectly with my old version.

try resaving models?(open model in med, then save?)

Check the player's skin 1. The player can be white when its first skin has no texture, or no mapping, or an all-white material setting.

still doesn't work

Can you describe the model, its skin settings, and the circumstances of the problem, possibly with a screenshot in MED and the engine? Otherwise I have not many clues what you're talking about.

have you applied a shader OR material to the player model? this actually can be one reason that I myself experienced with shade-c for eksample.

The players Origin is outside the walls/floor?
