on gmod some of the npcs and playermodels have a missing eye texture. its only on certain npcs and playermodels such as black mesa npcs, deathstroke playermodel. i tried disabling all of my addons except for black mesa npc and deathstroke playermodel and problem still occurs so im gonna assume that it isnt the addons causing this.
Verify the Garry’s Mod cache.
Put -dxlevel 95 in your startup parameters through Steam. Garry’s Mod DX8 eye overlays are broken.
