Start by setting up your lighting scheme in Blender. This is what your cockpit or subject will look like when looking at it in the Material Viewport if using only the normal white light. | Start by setting up your lighting scheme in Blender.

You can set up your lights to mimic the 3 color channels used in the shader and thus bake three different light sources into three different channels in one bake session if you wish. This is what you might expect to see if you do a light source per color channel (rgb). | You can set up your lights to mimic the 3 color channels used in the shader and thus bake three different light sources into three different channels in one bake session if you wish. This would eliminate some steps in Gimp during the next part of the process, but for the purpose of this tutorial, we'll take the longer approach so you can see how it is possible to work with images and their channels.

Create the light sources you want to map (bake) in your blend. You can have up to 4 lightmaps per multi-channel light map in FlightGear. Each of those four lightmaps can be a single light source or a combination of light sources. In other words, you could potentially have 2 lights on the left combined into one lightmap and two on the right into another lightmap, leaving 2 channels open for 2 more lightmaps of any configuration. | Create the light sources you want to map (bake) in your blend.
