Nested Voronoi Fracture dyamics crazy

Recommended Posts

Hi all,

I'm trying to pick a couple of locations on an object that will have a higher density of fractures.  So, I put the whole object in a voronoi fracture, then use a mograph weight tag to select a few of those fracture.  Then i nest that whole thing in a voronoi fracture, using the mograph weight tag to drive where it'll be fractured again.

 

Dyanmics work fine with the initial fracture, but as soon as I turn on the upper level fracture, it freaks out (fractures fly apart).  This happens whether or not I restrict it to the mograph weight tag.

 

Any thoughts?

 

Thanks!

Have you watched this week's Rocket Lasso, in which Chris built a meteor / comet using pretty much exactly that method, and showed how to solve all the problems ?!

Wow, just watched it.  That was really cool!  It doesn't 100% solve my problem, but it DID lead me try something:

I switched the dynamics tag on the higher level fracture to Inherit tag: none, and that fixed it!

Ah excellent - I may have fallen asleep in that part of it myself, but had vague subconscious memories of him having a lot of issues to solve...
