Interactivity in threejs + Blender: static shadows on moving objects
Another hack from this project.
I wanted to have the shadows from the wooden support fall onto the moving wheel.
Baking them into the wheel texture didn't work because the shadows would rotate around with the wheel in an unnatural way.
Removing the shadows completely felt too flat.
The tl,dr: bake the shadows into their own transparent texture and then load that onto a plane that is positioned just in front of the wheel.
