thanks for all the help!
Workflow for quite a while has been to just map flat straps with UV, mesh and then flow.
Rhino 6 stopped doing this so I keep going back to to Rhino 5 which keeps UV planar mapping intact which can even be remaped later in other render software.
A great time saver!
I’m still not losing hope that it can be done in R6 or R7.
Cylinder mapping occurs sometimes, but are a minor headache and is better avoided…
@BrianJ I will send you over the .3dm file!
