I stated up my Jedi academy, and it looks like this: Please Help.
Something's screwing up your shaders. Remove all models, maps and skins you've downloaded and put 'em back in one at a time, testing each one. When it goes funky again, you'll know which mod caused it. And then all you gotta do is stop using it.
ok, 2 more questions, if that is ok:. 1: I have a few mods that seem to not play certain sounds that they should (such as a gun not making a firing sound), but when I open the Pk3, a firing sound is there in the directory with the working sounds, why is it not playing?
2: Is there a way to modify the speed that the bullets/rockets/energy travels?
The sounds problem is probably a conflict between mods. If you have two weapon mods that replace the same weapon, JA will throw a hissy fit. As for the projectile speed, I believe that's coded.
