I’ve been working on fixing a ton of lightmap-related bugs for the night time battles in Gratuitous Tank Battles. At one point, it suddenly occured to me that something that wasn’t glowing in the dark, and should be was the internal cockpits of some of the larger mechs.
Tada! (decided to test it in green)
This effect took way more effort than you would have thought, and possibly slows things a tad, I will do some more optimising nearer release. I think it looks quite cool though. And yes, the player can customise the brightness / color of the cockpit just like any other layer in the mechs. Support for lightmap attachments to a layer should also mean that modders will be in paradise, as you could have all sorts of Tron style glowy effects on units if you really wanted it :D
