Ruined water

The water in my Gmod has been pretty much ruined. I don’t know whether it’s due to a dodgy addon, the directX controls, or just a bug, but the water appears as either a white plain, a black plain, or a purple/black checkered plain. And underwater, visibility is next to nothing.

Can someone help me find a way to change it back to default?

Bumped, because I REALLY need help with this.

Possibly missing textures. Best thing i can guess as a fix is to do a fresh install of Garry’s mod.

It’s worked on some things, but not on others. The TF2 maps suffer from this as well.

Maybe it’s a DirectX thing? I had to adjust it to see a certain model in the toybox.

I’ve fixed it! All I needed to do was reset my DirectX back to 9.
