Hi, can anyone help me achieving the following:

I have a hollow metallic box, and a simple emitter shooting spheres at high rate at it.

I have Glue constraints turning to Soft constraints, also using rbd constraint from rules and rbd constraint properties. I can achieve denting(deforming) of that metallic cube, but I can’t achieve destroying it completely by tearing it to pieces all over the place. No matter what I do the steel cube just keeps deforming inwards like a wax or rubber and it seems like I can’t break Soft constraints holding pieces together. I tried using bullet rbd solver with break thresholds set to some super low values but it still won’t break/tear off.


To summarize - I need to destroy a cube in this way:

1. The first impact of the bullet just makes the dent (deformation)

2. Second impact to that particular place tears off surface in that area.

Can anyone help or hint me with how to achieve this effect please? Thanks a lot!
