Hi,
Im working on some kind of a mechanical machine. I don't have a very clear goal, I'm just trying to make it as procedural as I can.
In this video you can see a few chains and gears. I have a HDA for each chain, with it I can control the placement of the gears, their size, number of teeth, the teeth shape.
The size of the chain links and their number is driven by the gears radius. And there is a single parameter to rotate the chain and the gears.
I will continue to add more stuff to it. Maybe taking it to a steampunk style machine.

OK, I think it will be a flying machine. I started working on the rotor. The blades can rotate in two ways.
I think the mechanics are working, and I just need to add some details.
