Lumen shadow black in new Big Medium Small kit.

The new Tokyo Back Alley kit from Big Medium Small is finally complete. I’ve had a lighting issue with this kit from the start and I’m not sure if this is them or me. All of the assets from this kit seemed to be geared more for path tracer rendering than Lumen. Whenever one of their assets are in the shadow of a sunlight, it goes black. The pathtracer render has the right colors and tones in the shadows but not for Lumen. Any ideas on what is causing this? My other assets don’t have this issue, just the ones from that kit.

i’d guess the pathtracer picks up more ambient light from the sky. lumen does not unless you trace insane amounts. the cheat for that one is is using a skylight.
