A low detailed cartoon style motorbike based on the Triumph 3HW Army Bike.
I have kept this flat shaded and I modelled everything, including the tire treads, chains and springs. All the parts are geometry and it’s one of the reasons why its poly count came in as being quite high, but baking the tire treads to a normal texture and some basic repotology on some of the parts would reduce the poly count a great deal.
Whilst it’s straight forward to animate a chain in blender, Sketchfab does not support empties, so it can be a little tricky showing some animations when importing them. Specifically, animations that not only are driven by empties, but also follow paths, as chain animations do in Blender.
So this took a process of trial and error, several attempts, but finally using a path, empties and attaching bones to the empties I finally got the animation to work in Sketchfab. I did also have to bake the animation before importing.
