GTAO is broken

[anonymous_user_b2b3bc98]

Thanks to this thread, I was able to fix it by diffing it with UE5 source code. The fix is surprisingly easy. In “Engine\Source\Runtime\Renderer\Private\CompositionLighting\CompositionLighting.cpp”, function AddPostProcessingGTAOAllPasses(), change the following

		if (bSpatialPass)
		{
			CurrentOutput =
				AddGTAOSpatialFilter(
					GraphBuilder,
					View,
					CommonParameters,
					CommonParameters.SceneDepth,
					CurrentOutput);
		}

to

		if (bSpatialPass)
		{
			CurrentOutput =
				AddGTAOSpatialFilter(
					GraphBuilder,
					View,
					CommonParameters,
					HorizonSearchOutputs.Color,
					CommonParameters.SceneDepth);
		}

Hope that helps!
