Rigid Body Issue

[thrive]

Hi all, I was wondering if someone could help me sort out an issue I'm having with rigid bodies in maya.

I have a created a bunch of rigid bodies but a group of them have some how been screwed up. They will react to the same fields as the other rigid bodies but they wont collide with them nor any other rigid body I create to test with. They only collide with each other. Its like there on another plane of existence or something. How do I make them collide with the other objects in my scene? Any ideas on what the problem could be?

Thanks for the help.

chek the collison layer attribute of the rigdbody and set it to 0
