Find out ObjectRef's ID? I currently use linear search in minetest.object_refs, is there a better way?

How to find if an object that an ObjectRef refers to no longer exists?

With 3D models, can I make a model that consists of several parts that can rotate separately? I currently use yaw to rotate the whole model.

Except with attaching, you can't, multipart models aren't supported. Vertical rotation (pitch) is even less supported. :P
