Breaking Glue Constraints - Bullet?

Recommended Posts


If you have glue constraints network (using Bullet), it's possible to break them using a colliding object (e.g. a moving sphere that is flagged as animated static). However, is it possible to break them using abstract forces (e.g. using field or fluid forces, or even uniform force)? I've tried many types of forces, but regardless of their strength they don't break constraints. I've noted that packed pieces don't have "F" attribute, neither the Glue primitives (i.e. impacts = 0)? I only get impacts if I use collision geo, and "F" I apply POP forces...

Another related question: in addition to breaking constraints by colliding object, sop solver, and geometry wrangler, Is there another way to break glue constraints?

Just a quick update, I can actually break constraints using targetv and pop force...it's just requires "big" values and constraints should be "somehow" easy to break (e.g. if I break some constraints, then the rest won't be able to withstand the force)...I guess, using a collision object is the safest and easiest way to break constraints...


Seems like the only way to break constraints is either manually by placing them in broken group or a colliding object...

Yet another update if someone is reading: it's possible to break constraints using forces, basically use v@force at each packed primitive and if it's strong enough it will break the constraint. Note, initially I've used force dop nodes and they did not break the constraints, but when I replaced them with v@force constraints got broken nicely...
