Guns turn shiny bug?

Well, this is probably an addon problem, if it is, which one, but still, a few days ago many of my things, such as all weapons and certain NPCs, on Garrys Mod turned all shiny and metallic…I was really hoping not to have to clear out all of my addons, so can someone help me?

EDIT: Lots of fucking help you people are. Fuckers…

EDIT: I fixed it. Twas a conflict with some Ep1 materials. Also, please note I call EVERYONE fuckers. I call my best friends fuckers, so basically, Im calling you people- Lol. This also means Im a fucker. Great.

Turn HDR off, that might fix it.

You can’t expect people to help you if you call them fuckers, within a day of posting in the wrong forum(help forum). Turn of HDR or bloom.

Too much phong.

Turn off HDR or bloom as everyone said.

LOTS OF FUCKING HELP THE OP IS BY NOT PROVIDING A LOT OF DETAILS. Fucker…

I think um…
Type buildcubemaps in console and restart the map your playing on.
