Help

Maximum elements per GPU buffer, for example 4k elements would restrict a float buffer to be 16k maximum per buffer. Note: If you request something smaller than what will satisfy a single unit of work it will be increased to that size. Default 0 which will allow the buffer to be the maximum allowed by the RHI.

Usage

Unreal console (open with ~)
> fx.Niagara.Emitter.MaxGPUBufferElements 1

Console variables take a value. Replace 1 with the setting you need. Run it with no value to print the current one.
