i created a gray scale outline from the diffuse map of what i wanted to give some depth to, and i only used 2 shades darker than my neutral background. I'm only doing it on 1 texture the ship is using but its all over it (helheim01a fyi) I'm not sure if I'm saving it in the right format. I *think* i have the idea down but once ive saved the map, i'm not seeing that its doin anything.
I've got a Hecate mk 2 (i forget who made it, please forgive meh) I decided to try my hand at this normal map thing again. The FreeSpace Universe Reference Project.
