The devs put in an update for lumen that allows for correct colored refractive shadows to be present in the lumen scene, meaning they’ll cast light correctly in GI and reflections. Unfortunately, the same isn’t true for GBuffer shadows, which can (at their highest quality setting), only be greyscale translucent shadows. All of this obviously comes at an astronomical performance cost, too.
Big thing though, it doesn’t work for Megalights, so you’ll have to disable them if you want the featureset.
