How to reproduce:
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.
