KingMassen What/which segments are you using? and with which shader?
If they are "black" when doing a test run it is almost always the shader or
not correct textures for that shader, one or the other
If the entities are "bright" when testing the shader again is the cause.
There is nothing wrong with that shader, you just need to correct the textures.
Most likely the "specular" is set to bright?
First, which segment is giving you problems? Is it stock or custom?
My games never have bugs. They just develop random features..
Lots and lots of random features...
