Black models?

Hi, recently ive been having a problem. When i start up garrys mod and load up a map, all the models are black unless i look in a certain direction. Its kinda annoying…because i actually want to see what im using looks like.

Thats looking into the no shadows spot. Also does anyone know what those lua errors on the side are?

Why are you using the portal gun? It doesn’t work anymore in Gmod.

It was a portal gun physgun reskin.

Is this a problem on all maps or just a few (or just one)?
