How to make a ground crack animation?

Like how would I animate it in a way where I could have a heavy object drag on I and split the ground underneath it?

Get the rigid body constraints add-on, cell fracture part of the ground, add strong constraints to the broken pieces using the add-on, create the object to be dragged, make it an animated, passive rigid body, and then animate it through the area of the ground plane that you want to be broken.

Is that the “Bullet Constraints Tools” by bashi?

Took longer to find it than it did find it; thought, I’d seen it some time past. :slight_smile:

It’s older but still works…

Dave, Yes, that’s the one. I’m thinking of putting a tutorial together for this in the near future as well.
