Hello. I have a couple of questions about mapping. I'm using gtkRadiant 1.5 1)Whenever i rescale my skybox's size beyond a certain limit, I get a 'mirror plane/degenerate plane/bad normal' error (same as here). I have seen that other maps have very big skyboxes, therefore there must be some way to avoid that error. 2) I've put some trees in a map, and i can see both the trunk and the leaves in Radiant. When i test it ingame, I can't see the leaves,just the trunks.
