problem

I really want to make a video with gmod, but a strange glitch is getting in the way. When i try and use certain object, like tf2 hwm ragdolls, portal models, and a couple of half life 2 npc’s, it gives them a strange, almost cel-shaded, look. It’s getting really annoting. help?

Don’t forget to post computer specs as it helps a lot.
