◆ InitRHI()

void FTextureRenderTarget2DResource::InitRHI ( FRHICommandListBase & RHICmdList )

overridevirtual

Initializes the dynamic RHI resource and/or RHI render target used by this resource. Called when the resource is initialized, or when reseting all RHI resources. Resources that need to initialize after a D3D device reset must implement this function. This is only called by the rendering thread.

Initializes the RHI render target resources used by this resource. Called when the resource is initialized, or when reseting all RHI resources. This is only called by the rendering thread.

Reimplemented from FRenderResource.

◆ ReleaseRHI()

void FTextureRenderTarget2DResource::ReleaseRHI ( )

overridevirtual

Releases the dynamic RHI resource and/or RHI render target resources used by this resource. Called when the resource is released, or when reseting all RHI resources. Resources that need to release before a D3D device reset must implement this function. This is only called by the rendering thread.

Release the RHI render target resources used by this resource. Called when the resource is released, or when reseting all RHI resources. This is only called by the rendering thread.

Reimplemented from FTexture.

void FTextureRenderTarget2DResource::UpdateDeferredResource	(	FRHICommandListImmediate &	RHICmdList,
		bool	bClearRenderTarget = `true`
	)

overrideprotectedvirtual

Updates (resolves) the render target texture. Optionally clears the contents of the render target to the clear color. This is only called by the rendering thread.

Convert the input values from the editor to a compatible format for FSamplerStateInitializerRHI. Ensure default sampler is Bilinear clamp
