Lightmass: multi-bounced sky lighting

Thank you for your hard work!

Out of curiosity. I am recently experiencing this issue when I try to build lighting from your testing level

Swarm log:
11:16:49 AM: Processing…
11:16:49 AM: Couldn’t gather the requested number of indirect photon paths! 0 gathered
11:16:49 AM: EmitDirectPhotons complete, 0.000 million photons emitted in 0.1 seconds
11:16:49 AM: EmitIndirectPhotons complete, 0.000 million photons emitted in 0.1 seconds
11:16:49 AM: Marking Irradiance Photons complete, 0.000 million photons marked in 0.1 seconds

Im new to this and still trying to figure out how to post a image.

This indirect photon path issue also makes the final rendering looks wired with incorrect light bounces.I wonder if anyone else is having this issue as well or is it just me.
