I was going to post this lovely map I had map a while back. Well, since it had been made awhile back I took it upon myself to use a few new mapping skills (cough) and improve what I had already done. Mind you, the map worked fine before I started screwing with it.

Below you will find three solids:

Top solid is obviously sky texture
Middle solid is the upper canal wall
Bottom solid is the lower canal wall

Ok, before I "fixed it" nothing had been vertexed and the walls at the intersection and turns were sticking into each other. Seemed to work fine but I would prefer that all my vertexes are aligned and the map is all tidy.

Well, when I get done with this grand overhaul and modification of the skybox.......i get massive portal errors. Spent two days tracking down exactly what was going on. It all worked before.

If you take the middle piece out it all works fine or if you take the top and the bottom piece out it seems to have to no errors at all. If you turn the middle block into a func_wall, func_brush, or func_detail it's all good until you try and seal the obvious hole and then you get pretty much the same portal errors. Any kind of tool brush I can put there to make this problem go away.

Never really tried this shape for a skybox before so I am not sure what's up. Its shaped exactly the same way on both ends and no I haven't copied and flipped anything. I have thought of all the obvious fixes including ghosts. I copied the whole map into new.

Last note: oddly if you delete the brush left-top from the top lit brush--the error goes away as well. Is it in that corner somehow?
