Hi there,

i am new to houdini apprentice, but have long experience with maya and more recently blender.
i can`t seem to figure out the proper way to set up a scene where let`s say a plane is animated and then at some point the solver takes over and simulates a prefractured geometry collision with the rbdbulletsolver. I found a tutorial on doing it with a dopnetwork and the active value, but for some reason the rbdpacked node does not work with fractured objects, even if i set it up like in the tutorial. so its two questions really.
1. why does the object not fracture with the dop network ?
2. how to do it with rbdbulletsolver ? ( animating active and deforming values ? )

Thanks

It seems to me you could b missing an assembly node.
If you provide the file, I can have a look at it.

Hi,

i figured out the error in the dopnet, thanks !
but could you maybe tell me, how to setup the animation to simulation handover properly ?

use RBD Configure SOP
there you can animate your active, animated, deforming, ... values

Bullet Solver SOP by default updates those values from sops so they will pick up your animated changes
(can be adjusted in Properties/Override Attributes)

if using RBD Packed Object DOP directly, then you can turn on Override Attributes From SOPs and tweak the list if needed

thanks a lot, will try !
