I don't know how to paraphrase it, but at the end of the video Wayne takes the rig and adds it to the “TURRET” collection. But this rig is already in the “Turret_RIG” which is in the “TURRET” collection. Now the rig is once in the “TURRET_Rig” collection and “loose”.
Somehow I don't understand this. Is that good for something or is it for the overview or just personal style?
