[UDMF] Rotate textures

[Accensus]

Currently it's possible to rotate only flats. Could there be a way to rotate textures, too?

[Graf Zahl]

No. Wall textures need to be drawn perfectly vertically so rotation is not doable.

I see. Oh well. Back to good the ol' rotated textures workaround. Still, thanks for the info, Graf.

Could rotations of 90, 180, and 270 be done? It would keep everything vertical.

You can do those through TEXTURES. The thing is, the wall drawers cannot be easily adjusted to arbitrary texture read order, in their current state they are completely dependent on the original texture format.

It may be worth investigating if it is feasible to get away from the classic span drawers but I believe they still have performance advantages (but on the other hand, we have already seen with the old assembly that old assumptions may no longer be true.
