Hello everyone, Wondering if someone has suggestions on how to achieve this level of details with Houdini? I tried with grains, displacement, geometry, textures... I can't seem to get it to look right. VDB's seem to be quite versatile to achieve some of the general textures and shapes, but the end results is always too round and soft. Looking for: - Fine powder - Sharp cracks and fractured pieces - Mix of smooth and crumbled / rough areas - Small random chunks Are there suitable techniques I am missing or out of luck for this level of details? Thanks!
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 !!
Hi guys, I would like to creat this kind of powder effect wihtout killing my computer with dreasing too much particle separation of my popgrain... Perhap an other way to do this?.. https://www.pinterest.fr/pin/488922103292391449/visual-search/?x=13&y=13&w=409&h=518 Any hint? Thank you matierePoudre.hip
