This is a model that I made for a videogame that I making by my self.

The model is on parts and I made it with simple geometric figures like boxes, cones,
pyramids..., then I modified by
boolean operators.

I used real fotos for reference, and I got a plane of the real structure from the front, this was help me much.

At the end, for render, I used scanline renderer with 8 direct lights and one omni.
