Overridden from UNiagaraDataInterfaceBase

  Type Name Description
Public function Virtual Const void Override this method to provide parameters to the GPU (SRV / UAV / Constants / etc) The most common usage will be to provide a single structure which is nested with other parameters.

Overridden from UObject

  Type Name Description
Public function Virtual NumCellsCellSize MaxNeighborsPerCellValue ParticleNeighborCount OutputParticleNeighborCount virtual ... Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
