Thanks. One other question. Is it possible to flip objects with a key inside FPSC? I dont mean rotating them 180 degrees on an axis, but actually mirroring the geometry so it gets flipped? As right now Im including two versions of the doors, one for the left and one for the right, and then I've got 4 different colour variations on the bin, giving me 8 different door models / textures. If the user is able to flip geometry inside FPSC, then I could just provide one door and they could flip it themselves.
I dont use FPSC to make games, just to test my models, but if I was one of the programmers working on the level editor, these two options would have been one of the first things I'd of introduced
