UT3 Unreal Ed: Is there a way to turn a static mesh into a trigger Thread

<!-- / message -->

'Duh, I don't remember that much from UnrealED, but wasn't one thing that you have to create an interpolate actor to be used in Kismet? I think you'd just have to open that static mesh as interp actor to make it usable in Kismet. That's not for sure though, I'm not exactly an authority on Unreal. It just rang a bell and I thought I'd contribute what I remember.
Generally speaking I think any static mesh can be used in Kismet. It's just a matter of setting them up as the right kind of actor, not as static mesh in that case.

I believe that if it is an interp-actor, you should be able to 'touch' it in kismet. Take a look at CTF++'s Facing Worlds map - that has something similar in it, if I recall correctly. I don't recall using triggers on that one.
