I also made a few other tweaks, such as removing the 1-unit thick func_illusionarys that covered the walls. This means you can paint on the walls now.

Ultimately, my hope is that this will replace surf_pox on KSF.

pox as it is is very terrible and this would possibly make it somewhat ok, big + from me.
