    Hi, I am trying to get my particle systems to batch, but it doesn't seem to be working. I have all my particles on a single texture atlas, that all share a single material. And they have a uniform scale of 1,1,1.

    Like this guy did here:

    If you watch the video he is able to get his particles to render in a single draw call.

    Is this because he is using an older version of Unity and its not supported anymore? Or is there a setting in Unity that I'm missing?

    As far as I know, it is one draw call per particle system, which is not a performance issue unless you have 50+ of them?

    I see, so there is no way to batch all the child particle systems into a single draw call?

    Particles don't batch anymore. It now use a multithreaded system that does not support batching but should provide better performance.
