Hi All
This is a model I have been working on for quite some time now, only been doing it on the side.
The model is based on an accurate orrery model, so all the planets revolution around the sun is to scale. Textures on the planets also NASA textures.
I rigged all the gear through animation nodes add-on, so all of them mesh very well together.
Stills rendered with Cycles.
Animation in link rendered with Eevee.
