All my maps are fullbright

Specs:
AMD Phenom 8450 Triple Core
2.10 Ghz
3.25 GB RAM
MSI Nvidia GeForce 7900 GT/GTO

SO I cleaned out some addons yesterday. Some I accidentally downloaded with SVN. And now on whatever map I play they are fullbright.

I don’t remember what addons I removed since there where a lot of them.
But most of them where the ones that is standard in Gmod SVN Updater.

Try “mat_fullbright 0” in the console.

Thanks
