The DoomUnity skybox isn't rotated because my player prefab doesn't have that script added, but it also appears that doom skyboxes are horizontally flipped.

For examples to look at, there's some obvious missing sectors in freedoom1.wad (Line we used intersected holes), and I also found some malformed triangles in this wad: https://www.doomworld.com/idgames/themes/xmas/xmasdoom (first level.)...

Freedoom1 MAP01 is fixed, looking good!
