Issue with rotated sloped 3D floor.

[SuaveSteve]

I'm trying to get a rotated 3D sloped floor. Getting the 3D floor isn't the issue or the slopes, it's rotating it. Please look at the attached screenshot and UDMF WAD. Both the control sectors outside the main room have the same settings, except the ceiling and floor of the one on the right has a rotation of 90.

When I rotate, it seems to be pivoting around a point other than Selection center or Sector center. World origin works as expected, but is unpractical. So I have to give extreme values for ceiling and height through much trial and error if I want to try to align two sloped and rotated sectors.

I'm using GZDoom Builder (Bugfix) R2990.

The slope of the 3D floors are aligned with the control sectors themselves. So if you want the 3D floors to slope in a different direction, you'll have to put the control sectors to another part of the map that aligns with the new slope you want.


This is what it looks like from the side.
