Working with the UT4 build (UE4.1), I’ve noticed that sometimes if I save the level I’m working on, close the editor, come back to it tomorrow, some of the more complex brushes will be missing.
Here’s a map I’ve been messing with a bit:
And here’s the invisible brush selected.
In the perspective viewport, I’m inside that subtractive brush, looking around. It’s… THERE, just… not in the isometric views? I’ve seen this happen in a couple different maps I’ve messed with. It seems to always be non-cube brushes, cylinders in this one, stairs in a previous one. Subtractive and additive… dunno. Ideas?
