Or, If you look in the submision thread I discribe most of the developement. The modeling is basically a bezier curve to form one lobe. Then duplicated round, and filled the gaps. Converted to a mesh and used the screw modifier to extrude and twist. A bit of maths to get them to match. Then unwraped them and applied a concrete texture for the bump. The end caps have a very simple concentric circle paturn tex map for the bump made from a “v” mesh with array and screw modifier set to just revolve, not extrude. The shafts were similar. Extruded curves for the bosses, then converted to meshes to extrude out the rest of the shaft. A couple of loops to position the splines, and then individuall face extrude and scaleing. Got the bolts from the factory. And then a lot of trial and error while I learnt some more about nodes. The flakes were a last miniut idea, again just extruded curves converted to mesh, and pulled about with a lattice. Bunged on the choclate from the jaffa cake, but dident have time to improve it. The way I had the nodes set, if I improved the look of the left one, the right one became reflective. That was when I ran out of time. After deciding the position of the reflction map very early on I dident alter it again. The ground plain I added later blocks the refection from the red arrow hence the differance in colours. Just added an extra emision mesh near the front, behind the camera to brighten it up a bit. I had tried to get the shafts lighter, but there are two diferent meshes in each shaft, one uv texture mapped, the other with procidurals. With my poor node set up, by the time I had matched the colours and added the iridesence? it had dulled them down.
Only had time for I think it was about 800 passes on the last render before the deadline, so the relection on the ground plane and where the screw threads meet is still a bit noisy…
Da Da.
Hope that helps.
ps, Mostly Cycles.
pps. I forgot the small booleans next to the bolt holes. Tried the standard modifier, and also the recent carve build, but couldent spot any differance in the solution or another way in that build to use carve. Ihey dident take a lot of cleaning in any case.
