Spawn RBD to Collide another RBD (SOP)


Fakit

Recommended Posts

Hello all,

Maybe a dumb thing, but I can't figure it out right now.
I rebuild a simple setup to understand the issue (you will find the file attached)

I have a simple wall that I want to break (RBD SOP)
I created a sphere emitter on the other side, with RBD bullet solvers too (RBD SOP), and switches ($FF%20==1). Plugged this one into RBD (wall) for collision.

Issue : Only my first sphere is taken in account. 

1) Do I need to use DOP ? (didn't figure out the setup yet)
2) I guess as the sphere are spawn over time, the solver can't understand the data ? 

Let me know your thought. 

Thank you :)

@vicvvsh Thanks a lot for your quick answer and your detail file! 
Really appreciate it!

It makes a lot of sense now.
I never thought about deactivating the "emit rbd" for the wall. 

And you're right. Why bother with group and wrangle, when we can only use the embedded bounds in the RBD configure to activate pieces.

Thank you again :)
Have a good day
