That is a possibility. It just seems a little strange to me that they would scale the entire model to make someone shorter or taller. And I imagine it would get a little tedious to have to set the scale on the model for every scene it's in.

Then again, they could very well have scaled individual parts for height, and what we're seeing is an overlap of all the base models. Seems like it would be useful to have for things like the switches toward the end of the Volume 2 intro.

Also, I'm not an animator so I might just have no clue what I'm on about.
