In this chapter we'll see how to set up the materials for the Gidiosaurus and the Armor in the Blender Render engine; in fact, although not exactly of the same quality as in Cycles, it is also possible to obtain quite similar shader results in Blender Internal:

Comparison of the Gidiosaurus character rendered in Cycles (left) and Blender Internal (right)

If you are wondering why we should re-do in the Blender Render engine, which is quite old and no longer developed and/or supported, the same thing we have already done in Cycles, there are several possible reasons: for example, no doubt Cycles is superior in quality but, compared with the scanline BI, its rendering is (and, being a path-tracer, always will be) slower; even with the aid of a render-farm, rendering times are still a money issue in the production of animations.

The previous screenshot shows, for comparison, only the top parts of two full shot renderings of the Gidiosaurus character: the Cycles rendering to the left...
