  • Did Maxon forget to update voronoi fracture with new sim system?

    Posted by Eric Pereira on September 7, 2024 at 2:06 pm

    I am trying to test the new Connector object with Voronoi Fracture to get something like in the documentation image I uploaded.

    I want to test the break property with mograph selection to only have breaking of the connector pieces of the voronoi fracture on certain parts, either using a mograph selection tag or a field.

    However, neither seems to work with the new rigid body simulation system applied to the voronoi fracture.

    Breaking ceases to function entirely once I apply the mograph selection from the voronoi fracture.

    Am I doing anything wrong?

    Also, this happens with the new particles emitter system as well.

    The voronoi fracture selection tags for inside edges will not allow an object emission to emit particles from the selection. But I can still clone basic emitters onto that same selection tag and emit that way.

    Did Maxon just completely forget to update for voronoi fracture?

    Hi Eric,

    I didn’t quite understand how you wanted to do it, but if I understand the goal you’re looking for, then the tutorial below at 31:09 contains techniques I think will be helpful to you.

    Let me know if this works with you.

    Thanks for the tip.

    That video is interesting. I wasn’t trying to use geometry glue, though, but just the connector object to break voronoi fracture using dynamics.

    I am actually able to use the legacy connector built into the voronoi fracture. It does allow for weight maps using fields.

    It isn’t quite what I wanted to use.

    The new connector object is completely useless for working with voronoi fracture to define where the breaking force is applied using any selection or weight.

    Maxon must have just not cared to integrate mograph properly.

    The new connector allows for more bending with the destruction. The legacy connector is more rigid, but I will have to make it work well enough.
