Right. You only need the Hiro figure if you want to analyze the clothing yourself. But if you are just looking to fit Hiro's clothing to a different figure, all you need is the .dat file and the clothing, and then you just use "convert to".

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
