CallbackHandlerParameter

FNiagaraUserParameterBinding CallbackHandlerParameter

Reference to a user parameter that should receive the particle data after the simulation tick. The supplied parameter object needs to implement the INiagaraParticleCallbackHandler interface.

GPUAllocationFixedSize

int GPUAllocationFixedSize

Reserve a fixed number of elements we can write per frame. Once the limit is reached we ignore further writes.

GPUAllocationMode

ENDIExport_GPUAllocationMode GPUAllocationMode

Sets the allocation scheme for the number of elements we reserve for the GPU. The number of elements reserved should be as low as possible to improve performance.

GPUAllocationPerParticleSize

float32 GPUAllocationPerParticleSize

Uses the emitter property particle count * this to determine the number of elements we reserve for write per frame. The console variable fx.Niagara.NDIExport.GPUMaxReadbackCount is used to cap the maximum. Once the limit is reached we ignore further writes.
