Particles going through mesh collider

Questions & Answers
1

I have particles that are being emitted which have an associated World Particle Collider with it set to collide with everything. I am having an issue with these particles passing through a material which is set as a mesh collider and appearing on the other side. This still happens even when I set the Collision Energy Loss to one.

Send Collision Message is unticked with Min Kill Velocity set to 0 in the World Particle Collider.

Are there any other settings that I should be looking at it to ensure the particles do not pass through the material?

I have tried searching through other topics for an answer to this, but have been unable to find a solution.

I had the same problem and although it’s a kludge, it worked for me…

  1. Add an empty game object
  2. Add a mesh collider and set the mesh to the object you are trying to get the particles to collide with.
  3. Adjust the scaling and position until it is just large enough to make your particles collide properly

you can obviously remove the collider from your original object

Hope that helps
