RBD problem with breaking objects

[Sabes]

Hello friends,

can anyone tell me if the general workflow to cluster pieces on a e.g. wall is correct in my case?
I simply want a sphere smashing trough that wall and break some clustered pieces off. 

Is there an more efficent way to do it? 

Another thing that bothers me:
Can anyone tell me why my wall is moving in the simulation? Looks like it is slowly falling through the ground.
I can't find the solution by myself. Hope someone is able to help and give a little info about this.

Cheers and thanks,
ebastian

For the falling piece issue the way to resolve that is fairly simple, just drop after your assemble sop a point wrangler and paste that into it.

if(@P.y < 1)
    i@active = 0;
else
    i@active = 1;

 

this will make the pieces near the ground inactive. 

For the clustering I have no idea since I didn't use this method for clusters, Im still sticking with the old one, but seems fine to me.

Worked, I was dumb and placed the wrangle at the wrong position. Have tried this solution earlier. Thanks for your quick help!

Hello, 
I'm doing something similar that's why i found your topic.

I would have like to know how to break the cluster pieces in other pieces as soon as they hit the ground. I've tried different things until now, but without any success..
If anyone has any idea, thanks!!
