Hey Semaphore,
Dynamically fracturing is something that is on the list to work towards eventually, but has not been done yet. You can follow any updates here: Trello
The second is deformable mesh simulation, but currently isn’t support that I’m aware of. I did find this on Nvidia’s site: https://developer.nvidia.com/sites/default/files/akamai/physx/Manual/MigrationFrom28.html
I’ve reached out to a couple of the devs that work with this code to see if they are aware of anything regarding this directly.
