Props are all Black!

[Silias]

Whenever I spawn a prop from Counter-Strike: Source, it appears perfectly fine. As soon as the prop is completely still, it turns entirely black. It doesn't happen with any other props, and I am wondering what might have caused the problem (I did compile an FPS config, I'll put the commands below)

Try messing with your graphic settings, like shader, model, or texture.
