Function Documentation

AddMotionBlurPass()

FMotionBlurOutputs AddMotionBlurPass	(	FRDGBuilder &	GraphBuilder,
		const FViewInfo &	View,
		const FMotionBlurInputs &	Inputs
	)

AddVisualizeMotionBlurPass()

FScreenPassTextureSlice AddVisualizeMotionBlurPass	(	FRDGBuilder &	GraphBuilder,
		const FViewInfo &	View,
		const FMotionBlurInputs &	Inputs
	)

If the override texture is used, check whether the output texture supports SRVs before assigning it, as this causes a crash in FScreenPassTextureSlice::CreateFromScreenPassTexture at the end of this function if not.

The OverrideOutput texture did not support SRVs, so we created one that did, but we still need to resolve the output image back to the OverrideOutput texture too.
