Please move the light source in the RWG previewer to make mountains appear correctly.

The location of the light source in the RWG previewer creates an optical illusion where mountains appear as sinkholes in the map viewer.

 

To see what I'm talking about, take a screenshot of the map preview, open it in an image editor, and rotate it 180 degrees.

 

An explanation of the phenomenon along with a very clear example can be found here: https://researchmatters.psu.edu/2016/06/16/optical-illusions-and-the-view-from-space/
