Hi Cristobal Arnold SiToA and each pointcloud lives under its own model. I have not saved the cache to the mixer, as it is faster to keep the pointclouds ready to simulate by unticking the lock in the Cache Manager.
I am rendering instanced geometry btw if that matters - it is easier to quickly adjust particle size without affecting the simulation this way.
