I ran the sim all the way through and it looks correct here. None of the burst
effect from the video.
Thanks for answering, Jeff!
Do the particles penetrate each other? They do here.
in your video example it almost looks like the particle count suddenly jumps....
Nope, the count is continuous.
Strangely, after closing and opening the scene, the burst effect at
frame 200 does not show up any more, meaning the particles overlap quite
often.
Weird...
Precision is set to 60 in the Simulate node. Am I missing some other
parameter relevant for collision?

Subject: Particle collision behaves differently after particle count > 4000
Hi,
I've got a simple setup here with "Simulate Bullet Rigid Bodies", where I'm
trying to fill a volume with small spherical particles (radius 0,1).
Testing 2013SP1.
As long as the particle count is below 4000 (for whatever reason), particles
tend to penetrate/clump.
Suddenly at the frame where the count reaches 4000, all particles push
themselves out of their neighbours at once, then simulation continues normally,
with no penetrations.
A bug? I didn't touch any simulation range settings.

Thanks a lot!
