Hi,
this is the result of lofting the facet edges to produce the scrolls.I reduced number of facets to 40 per coil
and made sure the seams of the bottle and the Can where not part of the subtraction as this ends up with
the facet edges in sections.
Thanks to Brian for the help with the node editor I've got it working with the quartz node so now I can run
the animation automatically without moving a slider.
Cheers
Barry
