Normal Editor: Map Overlays
The Normal Editor allows a different map, such as a color map, from the project to be overlayed onto the normal map canvas. To do this simply click the 'M' button located
under the Normal Map Canvas. This will bring up a selection dialog where you can choose the project map to overlay.
Once accepted the following overlay controls will appear.
The overlay controls allow you to toggle, change opacity, and remove the overlay map.
