Nah, skybox for me all the way haha
Usally all the the faces that face the void aren't rendered but when you skybox those faces that you don't see are rendered for they don't touch the void also it makes it much harder for vis and rad to render the map, vis needs to create more portals and leafs(may cause errors like- Max leaf faces, Max portals on a leaf, leaf saw in to portal, maybe allocblock:full and all these memory errors and many more) and rad will need to conculate the light on more faces(might also create many memory errors and some faces that were discarded before might cause a melformed face normal error)- Results: low framrates and high R_speeds might even be fullbright(if you have a memory error or a melformed face error) or might not work at all(all those leaf and portal errors), it's worse then a leak. If you do skybox then at list null the faces you can't see, all though it wont help you alot.
I think it should be a FAQ when there will be a section for that.
Simple way to defeat leaks is to map properly.
Explain yourself, ant. Do you mean by not using a small grid size?(like 1)
any other people proud of their battles vs. the leaks?
I had a few leaks in my unfinished compo entery. I had a 1 unit leak and I couldn't see it cause all the detail(and leak pointer and the point file didn't point at it) and the other was through a func_wall...I didn't even know I func_walled that wall.
