Hey thanks, that worked. I had tried with compare objects before, but I didn't know how to it set up properly until I read your post.
I managed it in an earlier mockup map, where I had already gotten triggering with kActor touch working, though now I'm for some reason unable to build the same set up in a newer map, heh. I know there's a checkbox hiding somewhere, either checked, or unchecked.
/edit.
Oh right, you have to first add the static mesh as static mesh and then convert it to kActor, instead of adding it as rigidbody. That was the problem this time. Funny.
