How do I get a rigid shape not to get back up?

Note: I copied this here because it wasn't being replied to after a few hours in the private section.

I tried a lot of things. I feel like I either need to look in the source code to figure out how to do it or modify the source code. I don't want to do this yet. Can anyone tell me how to do this? I'm using the rigid shape physics built into Torque. Not the vehicle physics, the shape physics.
