Fakefactory lighting error

So I’m trying to get fakefactory maps to work in gmod, and it all almost looks fine except there’s a lighting problem

Eli’s funky lab.

it’s all purple checkered lighting and I’m stuck.

That’s cool looking,

Oh it’s a missing material.

Build the cubemaps.

Tried that

Didn’t try that,

Try minimizing then maximizing the game.

Yeah this has to be it. You can see the distinct purple\black checkered pattern.

In the picture you will see a classic case of a missing custom env_projectedtexture texture.
