Ragdolls and props partially black

In Gmod, the props, ragdolls, and even the v_models are partially black or darkened. What should I do to fix this?

I have the same problem since the update, a few days ago.

Black faces and arms on NPCs and no colours on vehicles.

Same problem

Each update breaks more and more things. This happened to me to, as well as my TF2 ragdolls becoming low quality.

THE EXACT SAME PROBLEM, i have no idea why but theres blobs of black on the ragdolls, all my vehicles are completely black and even the props and stuff are all black, its really weird and i hope they fix it
