I created a motorbike model where a bone is turning the back wheel, but it is also driving an empty that is rotating the bike chain.
The chain setup is fairly straightforward. With a bezier curve path for the chain links to follow - these are driven by an empty - which in turn is driven by the bone of the back wheel (so everything is in sync).
The problem is I cannot figure out a way to bring the chain animation into sketchfab, so the wheels turn but the chain stays static.
I have tried baking the animation and also used a bone and an empty to drive the bezier path, but this doesn’t seem to work as the chain links always need the path so they can be animated around it.
But (as far as I am aware) sketchfab preview/render system doesn’t recognise empties/curves from blender.
I may well of missed something in the process, but If there is anyway around this or any suggestions for how to fix this it would be very much appreciated!
