It is just a mockup, I actually increased the contrast and for the color is just did a gradient map of the greyscale. I have noticed different materials I have used have a different looks in the IR view, but I am not sure what properties that is due to.
I am quite satisfied with Outerra's IR view, except there should be more ground contrast, everything is very flat in the terrain texture. It would be great to have a thermal map for aircraft vehicles, and a secondary thermal map for heating on certain areas. The secondary map would multiply the primary heat map in linear space. Like color * albedo, it would be ir_map * ir_hot_map, or something to that affect. The script could then increase the magnitude of the ir_hot_map over time with the engine on, and it would mix values with the ir_map. When the engine is turned of the ir_hot_map magnitude would be slowly decreased as it cools. That is just a concept, not really important right now, but it would be awesome.
I would however really like to be able to create a custom HUD, both for multi-stage rockets, and for missile seekers.
