Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere, Meta uint8: 1 bInheritUserParameterSettings When enabled texture parameters (size / etc) are taken from the user provided render target.
Public variable UProperty Category, EditAnywhere, Meta uint8: 1 bOverrideFormat  
Public variable UProperty Category, EditAnywhere, Meta uint8: 1 bPreviewRenderTarget  
Public variable UProperty Category, EditAnywhere, Meta ENiagaraMipMapGeneration MipMapGeneration Controls if and when we generate mips for the render target.
Public variable UProperty Category, EditAnywhere, Meta ENiagaraMipMapGenerationType MipMapGenerationType  
Public variable UProperty Category, EditAnywhere, Meta TEnumAsByte< TextureFilter > OverrideRenderTargetFilter When enabled overrides the filter of the render target, otherwise uses the project default setting.
Public variable UProperty Category, EditAnywhere, Meta TEnumAsByte< ETextureRenderTargetFormat > OverrideRenderTargetFormat When enabled overrides the format of the render target, otherwise uses the project default setting.
Public variable UProperty Category, EditAnywhere, Meta FNiagaraUserParameterBinding RenderTargetUserParameter  
Public variable UProperty Category, EditAnywhere, Meta FIntPoint Size  
Protected variable TMap< FNiagaraSystemInstanceID, FRenderTarget2DRWInstanceData_GameThread * > SystemInstancesToProxyData_GT

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
