SHINY AND REFLECTIVE TEXTURE GLITCH
so, I don't know exactly what I did, but I hit the restore button on the LIFE addon, and now suddenly all of the reflective and shiny textures are in checkers. not the striaght purple and black, but they are only visable from certian aspects. I have screenshots but I dont know how to get them onto here, I tried literally everything I could think of to fix it, re-verified my game cache, uninstalled and reinstalled gmod itself and the map, and pretty much everything in between. if I turn off mat_specular 1, (mat_specular 0) NOTHING is shiny, no custom content, like cars and skins and that sort. and that makes the game pretty much unplayable. HELP ME!
