Hi, testing vellum with geometry collision, default settings, looks terrible so far, a lot of particles are still inside the box.
Yellow areas are @stopped. Any suggestions on how to make collisions better?
substeps are not doing much

UPD: it was because of a CACHE MEMORY toggle, without this turned on collisions are not accurate

not sure but your ultra small pscale could be problematic ?

here's my simple test…works ok…but with smaller grain size…they start to go wonky even with higher substeps and whatnot…

I guess you right, just recreated it from scratch too, and it's working now.
thanks!
