Material opacity 0 #12
Description
I'm wondering if it would make sense for the picking texture to take material opacity into account. Maybe the expected behavior would be to render the picking texture only if material.opacity > 0?
This came up in a situation where I set a mesh.material.opacity = 0, but was still able to pick it. My current workaround is to set mesh.visible = false, but I think this is a hack, because an object might have multiple materials, and each material can have its own opacity (though I have no idea how common this is in practice).
