Hi, I'm trying to recreate the collapsing buildings from the H17 presentation video. I'm struggling on the part to break the soft constraints. Found a softconstaints example video in the documentation with breaking, but in order to get that to work, you have to use “Attach Internal Constraints to Object” option (network relationship) with geometrywrangle and removeprim() if torque is above a certain number, for some reason the hard constraints behave differently and I get bad results when I use that option. Anyone else experience with this?

Do you have a scene file for the approach you tried?

Hi…. did you ever find a solution for breaking soft constraints? Trying to do the same for rbd wood fracture material.

Cheers

Pipe a SOP solver into the third input of the Constraint Network DOP. Inside, add a Primitive wrangle DOP to the last input, (relationship geometry), make it the display SOP.

Use this code, (or something similar… you could use torque, or force, or whatever instead of distance):


IMPORTANT: Toggle off “Attach Internal Constraints to Objects” in the constraint network DOP
