I don't know. The GPU accelerated lightmapper for Unity looks quite promising actually.

And THIS is exactly why it's so powerful and useful

Your not jumping ship on us are you?

Yes, I think the core algorithm of UE4 lightmass needs to be entirely replaced. Photon mapping must be abandoned. It's a fairly obsolete GI solver which usually delivers weird light leak, incorrect illumination distribution and eats massive memory. Then use pure path tracing based solution instead, like Unity's new GPU baking feature.
