Distortion improvement progress

What is being lightened in that case is often a double image of the building. Moving your viewpoint between images requires some kind of artifact between foreground that moves and background that doesn’t. In city mode that artifact is doubling the foreground onto the background, in country mode it is stretching the foreground to the background. So the sky lightening also attempts to reduce that artifact, by presenting that doubling as an “after image” instead of reality.

The exception is when 3D building geometry isn’t sufficiently sized for the foreground. This most often happens in the height dimension, because GIS data doesn’t often include accurate building heights they must be defaulted based on type (residence, commercial, apartment, etc). So sometimes the tops of buildings will go by in the sky that aren’t covered by the 3D building. We’ve tried pushing up those default heights but could go further.

We can also play with the sky lightening amount, but if we disabled it completely you’d get something more akin to comfort mode above the horizon, and not be able to make out the 3D buildings. Maybe we could do a gradient lightening, but we do want you to see those 3D building outlines to appreciate what’s foreground and background.
