  1. RBD Jittering Velocities

    Hey guys, I've got this simulation of a wall where a train is wrecking through a wall. Some fragments hanging at the wall are still jittering afterwards. The jittering itself is no problem because it's minmal and the camera will be shaking. But the jittering velocities are a problem because they disturb our motion vector pass (generated through Maya Arnold) and cause it to flicker. Is there a way to leave the simulation as it is and "repair" the velocities? I tried a filter for the low velocity values, but they are not precise enough. I uploaded some Frames of the wall as bgeos: https://drive.google.com/open?id=1Re5YiuvD8KaTe56XRehdGMfcQmV9b8sA Thanks for the help!
  2. Hi there. I've got a basic thick viscous flip fluid simulation, problem is when it interacts with an Alembic with many holes the fluid seems to jitter alot and the sim seems to splash outwards. I reckon this is because of the change in the polygon count? This is my Hip file and the Alembic (hopefully not to big to be on this forum) if so I can upload it to dropbox. Hope you can help me out with this one. (also added a clip) Thanks, Y Fluid_sim_Test7.hip testAlembic3.abc JitterProblem_01.mp4
  3. hi everyone i have a small issue here with my sand grains (wet grains) - i'm trying to get my mesh to collide with them but they seem to be jumping about a fair bit as the character moves. I'm not sure what i can do to adjust this jumping about does anyone have any ideas? playblast below to show you what i mean. I cant share the scene file right now sorry but the jumping of particles is quite noticeable here ip.mp4
