I'm working on a simple animation to get 2 models (aeroplane and ground plane) to react against each other - i.e when they collide one bounces off the another.

I have tried to make a simple model group (a nurb object and some polygon objects) in to a passive rigid body (PRB), but I get an error.

I select the model group, soft/rigid bodies, create PRB, but no joy!

I created the model in Maya Complete then tranferred to a machine running Unlimited. Does this make a difference?

I re-created (in Unlimited) a rough prototype of the model, and the ground plane, created a PRB, animated it and it worked perfectly.

Can anyone help?
