nParticle collision with blobby surface mesh?

#1

Hi. I’m working on a scene with “small weightless beer drops” that has carbonic acid bubbles inside.
The setup is realitvy simple using nParticles with locators to control each indivudual drop.
The carbonic acid is solved by emitting nParticles from inside the surface of the drops and then killed off (kill drop, collision event) by a slightly larger drop (outMesh of the larger drops -> inMesh of nRigidShape).

The setup works great with no animation on the “drops” - but when the drops moves around the collision solver gets messed up. The nParticle collision solver makes twitches that is not happening in the outMesh of the “kill drop” - so it could be a bug or re-solving collision mesh is happening before collision event (or something like that).

Any idea on how to solve this or anyone has another approche to this task?
The scene file is included is here (Maya 2014): https://dl.dropboxusercontent.com/u/5671/BlobbySurface_012_cea.mb.zip.
Open and press play :slight_smile:

Thanks a bunch.
