Hi - I've got nice results with my WetSand - I'm just trying to increase the mass of the particles, and from searching it seems there is no node for this?

I tried POPProperty with no luck…

Any suggestions?

Thank you!

Found it - on the GrainSource node there is a switch called “compute mass” - and then you have to turn off the option to IgnoreMass on any forces you use…

Thx Cameron, just helped me a lot.
