Firstly, thank you to WNP78 for posting the craft generator script, it's really cool!

I've messed about with it a little and have noticed that portions of the aircraft may have inside out fuselage in areas, as warned, but would there be a way to quickly go through the fuselage and change it to normal fuselage?

Inside out fuselage
Negative value

These pictures are to show that to fix a fuselage part, you only need to switch the negative numbers to positive, but since there are so many parts, it would take quite a long time. Is there any way to quickly sift through them all, or would it be better for me to change the way I am using the craft generator?

Edit: the inside out fuselages are the ones that are grey and mostly unreflective.
