Mobile materials bugged

I tried the promoted branch, after building everything my pawn stopped spawning, leaving everything frozen and broken…

So now I’ve installed the 4.9 release, same thing happened, but this time my trees’ LOD models all render at the same time, I had to re-import and override to fix that. Then when I built the lighting, it bakes all the nice bounce lighting but there’s no direct sun light and shadows. I tried both static and stationary area shadows.
