All of the sudden, went to hop on GMod and work on a Tatra body, pulled out the materials tool and there was only about 20 materials. I looked to see if i could spawn/see HL2 props etc. and i could. Backed up my addons, and even with the basic GMod files, there were still very few materials. Checked to see if all games were mounted and it said they were. Not sure what to do? Any suggestions would be greatly appreciated.
