Another error with the slope rendering that looks really bad in my map; something goes horribly wrong with very steep slopes.

Made a little vid out of it (the second bit of it, there's also three other buggy parts of the map in the video.): http://www.youtube.com/watch?v=chyJmay--kI

I hope it's possible to fix it... I can't release the map looking like that. x-x

The first half of that video looks like you're missing wall textures. You can send me a sample if that's not the case.

The second half looks like the problem this bug report originally opened, which I honestly don't understand. It only happens if you rotate the texture. Maybe I should merge my changes into the trunk so I feel safe changing the way aligned flats are handled.

There are no missing textures as far as I can tell.

Hm, I'll just send the map via PM.

I'm just wondering: Does today's slope fix help here as well?

Yes, it does.
