More problems
It's not very important that I have these brushes there and if no way to make it work it's not such a big deal.
Anyway, I have a func_illusionary and it renders weird because part of the top face can be seen as normal and not texture rendering in some angles. I think it may be too large because if I make it smaller it renders properly. But can I surpass this? I can't work around the canvas of the room.
