Hey pumbaa, they were placed using the smart duplicate script from ticket01. Basically it allows you to project them onto the geometry using splines as guides and an underlaying surface as the control surface.
Hey Simon, I really enjoyed the part when your folio totally exploded my laptop screen. I am curious of a few things, but I'll only ask one q, the bolts on that fighter plane, which is epic btw, how did you place them all? Script? Paint geo? Thanks. Truly wicked work.
