I am working on a sequence where we show a future robot mission exploring an icy moon in gale-force winds.
We want ice growing on parts of the robot, breaking off, and being carried away by the wind in an endless feedback loop.
For the ice growing, I have a SOP solver that turns parts of the geometry into VDBs then using VDB reshape Dialate with a noise mask. Which has the growth look I'm after.
Then I'd like a subset of this to be fed into an RDB solver that shatters and breaks pieces off to be carried away by a wind force.
How do I remove these pieces from the SOP solver in a feedback loop?
Is there a way to chain a SOP solver and an RBD solver in a multisolver?
Any suggestions would be much appreciated.
Thanks
