Textures with transparency look odd on Android

[EddyVerbruggen]

If you look at the rings of Saturn in the image below, you can see the transparent part of the image is actually a little opaque.

@nickolanack Do you perhaps have any idea why this happens?

That might be a reflection/lighting. I think we could add

gltf.materials[0]["extensions"] = {
                "KHR_materials_unlit": {}
              };

to material factory to create an unlit material I don't think that we want to do this in general, but I'll experiment with it...

In the meantime, you could use a ~cylinder~ tube with innerRadius=0, and height=0 (or close to)

That actually works pretty well!
