In UE5.2, I’m getting the following errors. Any idea how to fix those?

System failed to compile with 5 warnings and 9 errors.

Update: Seems as if you have to pass the mip level now as 2nd parameter for the SampleRenderTargetValue lines in the RoughnessIntegrator like this:

RT_PixelAttribsA_Casc0.SampleRenderTargetValue(float2(CascPosX[0], CascPosY[0]), 0.0f, SampleValues[0]);

This makes it compile in 5.2 but the visuals are still completely broken.
