Another topic I want to talk about in the Space Lighting Tutorial will be the importance of Diffuse, Specular Maps on space ship models. How lights interact with Specular Maps most importantally.
I used 3 of Fabio Passaro’s textures from his Star Fury to create this image.
The image is a composite of three texture maps. The specular map breaks up the specular highlights, the diffuse map give different tonal levels to the color map.
Plan on going into a detail on that since it’s crucial to Lighting Space Scenes well.
