Broken Explosion Particles

This is a picture of my broken explosion textures. Does anyone know how to fix it? I’ve tried all of the following:

-Verifying cache files of all games associated with Garry’s Mod (including GMod itself)
-Reinstalling GMod
-Reinstalling TF2
-Reinstalling all of the Half-Life Series
-Screaming at my computer XD

Link to the picture if you can’t see it:

  1. Turn off Steam cloud sync for GMod (Garry’s Mod --> Properties --> Updates)
  2. Delete your download and materials folder.
  3. Take out any addons if you have any.
  4. Disable all workshop addons.

@code_gs Okay, I did that. Do I need to turn steam cloud back on after?
