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 Const bool

ShouldCompile ( EShaderPlatform ShaderPlatform
)

 Allows data interfaces to prevent compilation of GPU shaders and is only called on the CDO object not the instance.

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 void Called after the C++ constructor and after the properties have been initialized, including those loaded from config.

Classes

  Type Name Description
Public class FShaderParameters
