Megalights with Transluscency Ray Tracing causing metahuman faces pale white?

Hey folks, I came across this issue enabling ray tracing for both GI and Translusceny while also enabling MegaLights. Check out the video below.

Is it possible to keep ray tracing on for Lumen and transluscency while also enabling MegaLights. Any help in order to achieve all settings to work together would be hugely appreciated!

Thanks!

It appears that having substrate materials enabled makes this pale white effect. It’s a bummer that I have to disable substrate mats but I guess it’ll have be a tradeoff decision.
