So I found this NVIDIA GameWorks Increases the Pace of Innovation in Unreal Engine 4 Games | NVIDIA Developer

And I was wondering if this would fix the known problem of incorrect lighting on modular environments?

That’s two different things. This is a dynamic solution for GI whereas the one you’re referencing with color variations in modular pieces is related to Indirect lighting with lightmass.

If you make all your lights Dynamic it will resolve the baked indirect lighting variations you’ve noticed.

Cheers Tim, thanks for clearing that up :smiley:
