In this environment the number of object was pretty low, so, the textures needed to be a lot more detailed to hide the lack of geometry. Each diffuse had its proper normal map and specular map.
I’m not going to spend much on texture creation because 3DTotal already have a lot of great tutorials on this subject. Before creating any texture you absolutely need to fix two things: your camera POV and your render size. With this information you can easily track the right resolution of your textures. This rule will focus your mind to put the right amount of detail in the right places.
My texture sheets can be seen in Fig.21 – 22.
