There is one instance if this console command not working fully, In DOD:S everyone in the game is showing this issue, I type the command into console and it goes away, that it until you shine your flashlight on them and only that one person you shine your flashlight on in the game is effected until you stop pointing it at him, or turn the flashlight off.
so far in Gmod, TF2, HL2DM, it 100% solves it, DOD:S it solves it until you shine your flashlight on someone. but this effects no other source game or mod.
load up Gmod without typing this command into the console or without it being in launch options and spawn a NPC say like a vortigaunt, you should see this http://steamcommunity.com/id/madmax_2069/screenshot/577794895718065652/? and type that console command while looking at him, it should turn him back into normal.
It will never get fixed by posting it into a forum, you have to create a valve support ticket to get them to realize its a game engine issue. It would be years if you let valve fix it when they see fit or it might never get fixed, as it is now they are seeing this issue as a hardware failure related issue and not a actual Game engine bug.
