Particles collide inside a mesh

Recommended Posts

Hello everyone,

Sorry for the basic question but I just want to emit some bouncing balls inside a mesh with Houdini 15.5. To create that I just create a source particle emitter and I put it inside my collider mesh. I make the mesh a static object and increase the uniform division and click on invert sign in the static object node. But when I launch the simulation the particles have a very strange behavior. If anyone have some idea to achieve this.

Thank you for your response.

Hi! :)
The other day I watched stream with professionals from russian cg studio.
They strongly recommended to use manual SDF object(with Collision Source node) instead generating it in DOP(because,as they said,it works very bad or not so as you want).
So,i remastered your file(working perfect now),sorry for H16 version-i don't have 15.5.(

Hello Iskander, 

Many thanks for your answer ! I don't have Houdini 16 here, so I will check that later. :)
