Question batching vfx graph

Hi @laurentlavigne ,

You can send particle attributes like position or color using EventAttributes; this forum post has some examples.

As for the count, it is already set in the spawner's block (Single Burst) count. If I remember correctly, I don't think you can read attributes sent via script at the spawner stage, so if you want to modify the spawn number dynamically, spawn the max amount you could want and pass some attribute to store how many you actually want and then kill the rest off in the Initialize stage using Set Alive. Or you can also send multiple events (some work was done for 2021.2 where you can send multiple events in the same frame, something which was a limitation before).

 

Yup, the 1-event per frame should be the only limitation in 2020
