Why aren't my particle systems batched?

Questions & Answers
1

I have a texture atlas and one material. Three particle systems are using this material with texture sheet animation. I get 3 batches. The material is transparent. I am using 2019.1.2f1

If the transparency is causing the issue, can you tell me how to put an image onto an opaque material without showing the background? Thanks.

The Frame Debugger can answer the question “why isn’t X batched?”

Cutout mode on the Shader will render opaque with a yes/no choice about whether a pixel is visible or not (hard edges, rather than soft alpha fade)
