Thanks for the reply! I fixed auto exposure; however, it was still too dark. I looked through the HDRIBackdrop properties and found the Intensity parameter. By default it sat at 1, but increasing it to 1000 gave me the result that I wanted, but I'm not sure if it's the right way to do it.
Yeah the skylight/HDRI strength needs to be relative to the skylight strength, I've heard a ~4:1 ratio is normally suggested, but probably depends a lot on the particular HDRI being used. Using real world values can sometimes cause artifacts with other features like Lumen having black spots or a grid artifact, I think this…
