Description

Typing a negative Z unit conversion factor on the Base Heights tab for a raster, when its base surface is also a raster, results in an image whose top looks dark and the underside is light. The top should be light.

Cause

This is a known issue.

Solution or Workaround

ArcObjects Online contains a developer sample that can be used to factor the base raster surface.
