I need to know...did you make three individual meshes, or is it actually designed to transform? I look at these in my copy of the TRO over and over, trying to figure out how everything twists and fits together, and it's really bugging me!
The truth is actually somewhere in-between. There are common parts in each of the modes which do move from position to position, such as the legs/feet and portions of the nose and arms, those similar parts are used throughout the modes of each mech for continuity and do facilitate transformation. I had fully intended to make them 100%transformable, but with the time constraints I was under, that idea had to be sidelined. Thanks for the inquiry
