Help with 'Distance Field Ambient Occlusion' & Lightmaps / Lightmass

I’m starting to work more with Distance Field Ambient Occlusions. I’ve read through the documentation and it seems to be working well enough, but I’m having a bit of trouble understanding what the best practices are when using it.

I’m particularly curious about how it works with lightmass / lightmaps.

I tend to use skylights as a stationary or static element to bake lightmaps into my static objects. Would it be a bad idea to use a second skylight set to ‘static’ to still get lightmaps?

Really - just any ‘best practices’ for how to use Distance Field Ambient Occlusion would be of great help. Thank you!
