Hello;
Please look at image I attached here.
I would like to tear a geometry ( cutting to two pieces, during 30 frames) and use it as rigid body, So at beginning of simulation it is one RBD, but after 30 frames it will be two RBDs.
I set it to deforming RBD, but Houdini always simulates it as one piece RBD.

Can I cut a RBD to two pieces this way?


Thanks.

You have to pre-fracture the rbd object first and create cone twist constraints between pieces to make it behave like a cloth or bendable object.
Then break the constraints in desired pattern to achieve the look of tearing!.
