Hello. I had parts of a mesh dissolving using Niagara and Sprite Renderer in 4.27. Each material slot had a different emitter, and only generated particles for that area of the mesh.
When I migrated it to 5.1 the settings are all the same, but the Allowed Material Slots doesn’t seem to work anymore? It generates particles for the whole mesh for every material slot.
Is there something I need to change? Many thanks in advance.
