Asset Overview
A low poly style chain rigged and animated in Blender.
Whilst it's fairly 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 into Sketchfab. Specifically, animations that are not only driven by empties, but also follow paths, as do chain animations in Blender.
So this took a process of trial and error, several attempts, but finally using a path, empties on the path 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.
