The only mildly complex bit was the heat sink fins on the top of the
piston heads. First I polly modeled the basic shape. It quickly became
apparent that it was going to be impossible to model such complex fins
so I used a displacement map instead. It still needs work; some of the
fins should be longer, some shorter.
The gearbox is a polly modeled sub-D. Tubes are all splines and the
lower part of the cylinders are lathed splines.
I could get away with chucking some metallic surfaces at it, but I need
the practice texturing and the result is always better. Besides, Textures
are fun.
It's all 21st century Airfix.
165,418 Pollys total so far, but the render engine adds a few more
when it calculates the displacement maps.
First textures underway:
If anyone is interested at taking a look I can box it all up as a .obj or Max9 scene.
