Keep animation loop after PhysX actor goes dynamic

[falconking]

Hi!
I've been trying to make a simple scene with a simple rigged character. The idea is to make them fall and pile up. I was following the setup of the sample with the crowd and arrows, but I couldn't get the characters to collide with the floor. (But I guess that's a problem for another day) Then I tried following the example of the worms, now the characters do collide with the floor, but they won't animate no more. 

The actors appear in the pose of the first frame of animation, and they go into ragdoll mode right away. I would like them to keep on moving even when they have collide with the floor, and that they all push each other as they move arms and legs.

Any suggestions on how to achieve that?

Next thing I'm goin to try is to make the character out of max bones, since I am using Cat bones for this test and the worm example is with max bones. But not sure that would fix anything, it's just a wild guess.

Thank you for your time!

Hello. I have the oposite problem. My actors are animated but they go trough the ground. How did you manage to  make them collide with the ground ?
