tcMod uses a matrix uniform.

I suppose this isn't really relevant anymore, since `Render_generic2D()` does not exist now.

Hmm, so there are maps with more than 1 skybox. I think I know how to fix it in that case.

Yeah, I'm not sure yet what is causing that issue. On master though, you can see the whole room with those surfaces in that spot.

I fixed the above issue, but this fix seems to degrade performance considerably.

Ah, right, should be set to false. Still doesn't fix the performance issue however.
