I’ve made a few particle systems before but I’m trying to create an asteroid field effect and was thinking of using the mesh emission option in the renderer. While it supports multiple meshes (I don’t want all of my asteroids to look the same) I only see one material slot. When I try and apply the material, any mesh in the emission that doesn’t match gets a torn texture. Google searching hasn’t gotten me far and the documentation doesn’t mention how to set this up. Is it possible to use multiple meshes with different materials in one particle system?
In order to batch particles in the same render calls you can only use one material per emitter, this makes the particle system very efficient even when rendering meshes. All you need to do to alternate the meshes is duplicate the emitter for each type of asteroid (e.g each one that requires a unique material) and change the emitter for each asteroid type - then probably lower the emission rates so that you don’t increase the density too much. You could also use sub-emitters for when asteroids collide and you want to spawn debris
