This looks fantastic. Do you have any clue why this isn’t a native feature?

How long did it take you to implement if you don’t mind my asking, and are there any limitations or drawbacks to multiple bounces for SkyLights?

I’m trying to understand why Epic wouldn’t have added this feature themselves already.

Currently skylights are not handled with photon mapping in official Lightmass.

It should be better to handle them with PM, I think they simply haven’t got there yet.
