Nice to know that one can rotate brushes. It was forbidden in DromEd. But I noticed that when I started using free rotate option some warnings appeared in the console during bsp:
Not at all. Welcome to the wonderful world of Doom 3 map design, where there is no such thing as a "BSP hole"*.
Warning: BuildOptTriangles: couldn't locate opposite WARNING: backwards triangle in input!
I'm not sure if I understand... There was/is some "Unforseen Consequences" DM project/mod? Are there any screenshots?
Yes it is - a very stark contrast to the sort of things the Unforeseen Consequences lot were posting as their "just a few days with Radiant" screenshots...
