Opacity
Thanks for your suggestions, David. Actually, I was really trying to just
create a generic example for others — when I've had to do this myself either
the end wasn't a problem (it was off camera) or I selected and deleted the
face(s) at the end to achieve the effect. I just assumed at the time I didn't
know what I was doing, but got the desired results.
I really think the "end" effect is a bug of sorts — perhaps a rather esoteric
bug to be sure, but one nonetheless given the way things are supposed to work.
But as my major concern right now is modeling I think I'll worry about other
things.
