I’ve seen that in some maps like gm_wireconstruct_rc and other maps, that the floor textures are pitch-black until you shine a light on them. What’s wrong and how do I fix it?

Uh…texture problem?

there’s nothing wrong with the textures, since I can see them when I shine a light on them.

Go get a new computer no one else is having the same problem.

Well there’s your problem, an Intel Graphics Card…

Intel 915GM?

Not even 1 gig of RAM?

How is that supposed to run GMod?!

No offence intended,you need a new video card.
