Hi guys a have a flip sim colliding with a terrain oddly enough when the flip comes to a rest y forms this streak like shapes that look terrible i have stick on collision masked so it only sticks to the ground might that be the problem, i also have a bit of viscosity, my terrain colliding volume is really smooth and the vdb is hi res enough and i can't figure it out any help would be greatly appreciated
i've attached a pic of what is goin on

Diego.

please sent a hip file for analysing….

it could be this:
- vel is too high for the particle solver (try add substeps)
- terrain collition surface is to low or friction….

i'm not the old school master jeff so it's hard to analyse just from a pic. :-)
