H14 : POP grains + RBD : Dopnet cache changes sim massively

Recommended Posts

Hello all!

I came across something really curious today, I'm wondering if the hive mind can tell me what I'm doing wrong?



I have a simple fractured sphere using the bullet solver that collides with falling sand solver particles. With the Dopnet's cache turned on, the particles get hurled away at massive velocities. However, when I turned the cache off, the pop solver and rbds react exactly the way I expect them to.


Any idea what's up with this? I'm on 10.10.2, Houdini


I've attached the file in question here, at the moment it has the cache off, and the particles are doing what I expect.

However once cache is turned on, particle splatter haven begins...


Apologies if this has been covered!
