Grains - Disable Constraint Averaging

Recommended Posts

I posted this on the SideFX forum but haven't had any response so I thought i'd try my luck here:

I'm getting some unbalanced forces when using grains, its the same problem as described in the grains masterclass around 32:50. As Jeff says the solution is to disable constraint averaging and then insure all the internal forces add up to 1. I've done this but I still have an imbalance.. I wanted to check which forces are meant to add up to 1, in the video it implies that Internal Collisions + Clumping + Explicit Constraints = 1. However in the help document it mentions that Friction with Particles should be included as well.

So should I set Friction with Particles, Internal Collisions, Clumping and Explicit Constraints to 0.25?
