Hello,

this is maybe a really basic question.
Situation:
I have two packed RBD-Object node piped into a multiple solver node. There I plugged RBD-Solver and POPforce.

Problem&Question:
I want the POPForce affecting only specific packed RBD-Object. I tried with Groups, no luck. Then I put a Fetch Node before the popforce with no luck.
How could I solve this problem?

thanks
Tom

Can you post a simple scene - then we might be able to have a play to make it work.

Thanks!

each packed object has name attribute containing the name of each packed rbd piece
like piece0, piece1, …

if you have 2 of them just make sure name has different prefix so that you have unique names per each packed piece in the whole dopsim and therefore being able to group by name attribute in POP nodes

in the example there is torus packed RBD and box packed RBD, each of them contains currently 1 packed primitive with the name attribute torus_piece0 and box_piece0
and in the POP Force the group is set to: @name=box_piece*
to affect only packed pieces from box packed RBD

exactly what I needed. Big thanks !!!!
…such a great forum
