I was reading through the getting started docs for Niagara, and it states that emitters spawn particles on the CPU. Why bother spawning particles on the CPU when you are just going to move them to the GPU anyway?
P.S. I wasn’t sure which category to put this in, as it is more of a general system question.
You can choose in the particle main setup whether it runs on CPU or GPU. Some things have to run on CPU, physics ( I think ) for example.
you can spawn more particles on gpu but some features are only available in cpu sim, also don’t quote me on that but each emmiter takes gpu memory to store stuff and it might not be worth it if spawning only few particles
