Additional Information
This is by design. The shadows happen because a small amount of depth bias is added to the single-pixel outlines on polygons in the 3D layers group to ensure no z-fighting between the polygon face and the outline (to make sure outlines show up on top).Workaround
- A workaround is to turn off the lighting on the layer, which also disables shadow casting by and on the layer.
- In the global scene, move the polygon layer to the 2D layers. This changes the appearance of the layer but eliminates the shadow artifacts.
- Change the time of day to much later so there are no shadows, and change the light contribution to a higher value. This eliminates the artifacts but causes the 3D features to have poor-looking shadows.
