Thanks for the info. I wonder though....

The model I'm working on is a plane, and it is in .obj format, but I'll be turning it into a prop. The same for the landing gear doors.

So when I've converted the plane into a prop, will the landing gear doors have to be separate props? If I understand what you're saying, it sounds like that's the case. The doors I'll make as smart props, and when the plane is loaded into a scene, the doors will automatically show up with it, and if I've used the hierarchy editor correctly they'll be able to swing open or closed with the movement of a dial, correct?

Am I on the right track with it?
