Hi G,
I just centred them is all, and rotated them to 'forward' orientation.
I did the same for the ones I originally made the videos with which is why I'm surprised these ones ever worked with my scripts!
I actually need to re-write those scripts at some point, they still do things the 'old' way and could be improved to work with scaled versions of the models now that the Lua commands are available to do that.
Been there, done that, got all the T-Shirts!
