vellum grains, change amount of clusters over time

[sachacarletti]

Hey guys, I hope you are well, could you help me with something?

I'm trying to create a fracture of an object with vellum grains, I'm using clusters to create the pieces that I want to break and a mask with mops to trigger the simulation, but I would like to increase the amount of cluster over the simulation time, is it possible with cluster attribute?

for example, I would like it to break into large parts first, a few frames ahead, break smaller parts, and then smaller ones, and so on until it turns to dust

Thanks a lot if anyone can give me some tips.

I added a hipfile here

 

thank you!

@sachacarletti
Interesting .HM , how to make groups of that secondar cluster and where to assign those groups inside sop solver or before on sop level?? totalititus Blockout
if I have this code_

int pts [] = primpoints(0,@primnum);
int n1 = point(0,'__cluster',pts[0]);
int n2 = point(0,'__cluster',pts[1]);

if(n1 != n2){
    f@breaktreshhold = 10.2 ;
    }

int pts [] = primpoints(0,@primnum);
int c1 = point(0,'__piece',pts[0]);
int c2 = point(0,'__piece',pts[1]);

if(c1 != c2){
    f@breaktreshhold = .04 ;
    }

funny effects ..Thanx for a file Sacha
