But this affect how all other objects’ shadows are rendered as well. I only want to fix up these Plane meshes that I’m aligning with the DOM. It would make sense if I could use a different light just for the DOM elements, but “selective lighting” is not supported yet.
And then I’m back at Planes not casting shadows! 
I would really like these things to be solved in Three.js:
- Planes should cast shadows, which is something one can intuitively expect
- Selective lighting, which can help us achieve single-light effects which are actually composed of multiple lights.
