Hello,

I'm trying to parent a grid to follow the path of a RBD Packed Object. I have two problems.

1) I'm adding initial angular velocity and velocity to the RBD Object, but for some reason, it's not effecting the object.

2) I'm not able to parent the grid to the point of the RBD packed object.

I've attached my scene file.

Thank you.

Hi.
You are using RBD packed object with Houdini's native RBD solver which is not support packed objects.
You should use Bullet solver instead (hit tab in dopnet1 and typing bullet solver).
Parenting for object transformation in scene level not for object inside of geometry level.
If you play with all transformation options in geo1 node will see grid follows the cube.
