[Bug] Particle System doesn't work with 3D meshes anymore

How to reproduce:

  1. Create new project with default scene
  2. Create new Particle System
  3. Import some 3D model
  4. Apply it to Particle System’s mesh field

Particle system will continue showing whatever billbords it currently has, ignoring 3D mesh asset completely

Facing the same issue even today. Has anyone found the solution?
I want to use 3D mesh for Particle System.

Have you added a colour map to the particle effect? That’s needed for 3d mesh particles.

Also, keep in mind the vertex buffer has a limited space, so high-poly meshes simply won’t fit into it to be used as particles. Make sure the mesh has low polygon count.
