It looks like it worked for you.  Actually I was able to get a map not unlike
your roof design, onto the top of the nose section of my race car.
Unfortunately, my image needs to be mapped partially on the sides of the nose as
well.  When I scale the image with transformations beyond an edge of the
surface,  the image streatches completely down the surface like string cheese.
Kind of comical ( the first time...)

Because my surface contours arent exactly planar, or exactly cylindrical or
spherical, I assume I need to use, probably, planar but to cut my images into
sections for each orthographic view ( top, sides, front, back).  'Makes sense,
but it also gives one pause for the effort involved.  Wow.

I've been using a freeware program called UV Mapper to position my images on the
surface.  This part works slick. I import the surface I want to map from Rhino
into UV Mapper. In UV Mapper, I --unroll--the surface out flat.   I then
position and scale the image onto the surface.  I then save the "mapped" image
in TGA or GIF format (TGA) and copy that file to the Moray/Maps folder.  There I
can call up the image while building textures in Moray.

Do you see any problems with this method?

That would be welcome.  I'm not sure this newsgroup allows uploads, though.  A
zip attached to e-mail would work for me.  :)

Thanks for your thoughts.
