I love this forum.
I guess I'll have to "fudge" the dimensions. I'll see if I can't figure out an average of all interior meshes.
"GetBoundingBox"only works for projectiles and actors, so I can't use it. I'm placing everything except those two, basically. I can use this though, just guesstimate the numbers. Tedious editor work, but it is a solution.
I can get the bounding radius... the math will be different and I don't know how to get there.
