The modules are done in a 128 units grid so they match perfectly when put one next to the other. This way the building of the level goes extremely fast, and all the collisions are already in place once the modules are integrated.
In this texture each channel is used for different things.
The red channel is used for the details and specular map, while the green and blue are used to colour the texture, and the alpha for the emissive. This way I am able to create different materials and use the same texture for very distinct looks. The texture is also fully tillable.

I applied the same technique to do the effects on the screens.
