Collision shape in RBD Bullet Solver only shows Convex Hull? Jan. 19, 2024, 12:13 a.m.
This it Houdini 20.0 (don't have 18.5)
Constrain objects to fractured RBD pieces? Jan. 17, 2024, 12:20 a.m.
It's all correct.
I use pscale attribute randomize spheres' size and it was easy to use this attribute in an add sop to create primitives.
I created constraints as primitive with zero length in purpose to place these constraints between the top of the ground and the bottom of the spheres (not centroid) because that gave me more stiff and stable connection.
As for constraints_type - I just decided it more appropriate for this case, you can tray others values.

I poked around in the RBD Bullet Solver a bit. All geometry connected to first input of the solver (Geometry) has dop name "rbd_object" and connected to forth input (Collision Geometry) has dop name "collision_object". They and "groundplane" predefined in a RBD Configure sop in multiple selection menu of Collision Ignore parameter and in the others parameters. You can choose on of these name in that menu. Example attached.
