How to set properties for the particle system and particle set obtained through the particle sampler so that the generated particles are solid particles rather than fluid particles, and how to set properties so that the solid particles can gather into a pile instead of spreading all over the ground when falling on the ground?

Here is the current state picture. I would like to ask how to set the properties of the particle system and particle set so that when the particles fall on the ground, they do not spread everywhere but gather into a pile. Thank you for your help.

Hi @libindlut2007, thank you for posting this question and sorry for the slow reply. You can set Material to the Particle System. To do that follow:

  1. Create > Materials > OmniSurface (you can rename this material to make it easier to reference)
  2. Right click on the newly created Materials, then Add > Physics > PBD Material
  3. Go to the properties in the Material > Physics > PBD Material. Increase friction and damping.
  4. In Particle Systems Properties, go to Materials attribute and select from the drop-down menu the material you just created.
