Paint tool not working

I don’t know if anyone else has this problem, but the Paint tool isn’t making any decals on the maps! On props and ragdolls, it works fine, but even then, you can only have a limited number of decals before some disappear and I don’t think it used to do that.

Help?

if i remember right, in garrysmod 9 garry added a folder inside the material folder called “pp” inside the folder are files with cut the decals, blood…

Problem is you cant delete the folder in gmod 10/11/12/13 in gmod 9 you can.

So how does that help?
