Public function Virtual void

ProvidePerInstanceDataForRenderThread ( void* DataForRenderThread,
void* PerInstanceData,
const FNiagaraSystemInstanceID& SystemInstance
)

 Subclasses that wish to work with GPU systems/emitters must implement this.
Public function Virtual Const void Set the shader parameters will only be called if the data interface provided shader parameters.
Public function Virtual bool Allows data interfaces the opportunity to rename / change the function signature and perform an upgrade.

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.
