Here’s the problem, with an example
This is how the tube is supposed to look on the model
But when I choose one from the appearance menu, it shrinks back to a 1-1-1 scale,
I’ve also found out that everytime you change the appearance of your tube, it considers it to be automaticaly equipped from a tube rake
and when you put it back, even though you technically never grabbed one in the first place, it scales back to the intended size
so basically, Functional tubes have their metadata reset, and is equipped by default everytime you change the appearance of it
