  1. How to approach Flour in Houdini

    Greetings, I'm trying to achieve something like this https://www.shutterstock.com/video/clip-24306053-slow-motion-falling-eggs-into-flour-stock Forget about the eggs, generally I'd like to simulate a collision on a dust / powder like flour. First of all, how should I approach this effect? Particles or Grains? And if I choose Grains, should I use the normal Grain Solver or the Vellum one? On the picture below I have a setup that I used the standard Grain Solver, and 2 RBD object, on is the static plate, and the other one is the moving ball. I encounter many problems like the ball bouncing really hard on the flour, instead of just landing, and if I change the RBD Solver priority in the Merge, then the Grain collide merely good with the ball but they pass through the plate. So basically the Solver can't read both the RBD objects correctly. Also, after all, I need to use a custom Force to "Explode" some Grains in the air, because it seems impossible to happen with just the ball collision. Thank you in Advance !!
