What is the best way to put cracks onto an RBD Fracture object and have it maintain itself when simulating? When I put the cracks before the dopimport, the cracks will not show. When I put it after the dopimport, the cracks do not split or move with the pieces. I made a crack l-system that generates along geometry based on the thread below:

Attached is a simple scene that I’m testing this out on.

Check this attached File !

Looks like a great method, thanks!

On a sidenote, I’ve got a couple of simple l-system questions I’m hoping to get help on if that’s okay:

-The cracking method works because of the l-system generating straight up, but not with the crack preset since it is shifting directions. What are the best nodes to use to hold the l-system back onto the geometry? (There’s a crack preset l-system in the original attachment)

- When I set the l-system type to “tube” it no longer works with the method for some reason. I'm hoping to do this to make the tube thin over each generation.
