I understand these mechanics and have a fair understanding of the whole
process. It is the unpredictable results of unwrapping that I'm trying to
understand. Many times I look at the unwrapped image and can understand
how it was unwrapped but wonder why it was done like that when another way
would have made so much more sense and be so much easier to work with. It
seems Carrara has an unwrap algorithm that dose not follow human logic for
unwrapping a skin in the way most people would find useful.
I need to understand how and why it dose this.

Subject: [Carrara] Re: UV Mapping question
Carrara usually does not pick the best default projection for a given
shape. Go to the vertex modeler, select the object and open the UV
Editor. You'll probably see a distorted mesh in the map area of the
editor dialog. Look over on the right-hand side and you'll see three
tabs. Pick the one labeled "Projection". You can now play with the
way that the UV Editor projects the skin onto the object mesh. In
your example of cylinder, if you pick a cylindrical projection and
align it with the correct axis of your shape, you should see the
expected "long square" mesh in the mapping area. I think this should
solve your problems with exporting to PS & getting a bitmap you can
easily work-with. I may be completely wrong here, but is seems like
Carrara always selects a Box projection for the UV Editor, even if
I've already set up a shader and re-defined the projection in the
shading room. If so, seems like the best way would be for the UV
Editor to default to my shader settings? I'm just getting started
with the UV Editor myself & I'm still unsure about the relationship
between shader projections and the UV Editor projections.
