Niagara data channel islands prevent spawning more than a certain number of active particles at once

I have a new Niagara Data Channel set up following the NDC introduction pages, as well as the 5.4 update that follows, converted to spawn bullet trail VFX. However, when firing the vfx at a fixed point, the island will only permit a certain number of particles to be active at once, somewhere between 30-90 and will prevent spawning any more until these die. In some cases, they will prevent spawning any new particles until all existing particles have been killed, both behaviours which I can observe via the debugger.

This is definitely an issue I’m experiencing per-island, as firing the VFX in many different locations, I can have many more particles spawn. Below is the set up:

The StartLocation and EndLocations are not yet connect to anything. I was hoping you could assist as to why the island is limiting the number of spawns so. Any help would be greatly appreciated.

Thank you

Hey! There exists no such restriction on the spawn count.

How many entries are you writing into the data channel each frame? What did you set the min and max spawn count to for your spawn module?

Did you maybe set the allocation mode of the emitter to be fixed or set any of the scalability options?

Hi,

Unfortunately, the project was paused, so we can’t provide an answer and continue this conversation for now :frowning:

Ah, I’m sorry to hear that. Feel free to come back to this thread when the project continues.
