I have obtained a copy of Chris Colefax's Object Bender Include File
(Bend.inc). I was hoping that I might use it to bend an object after
applying an image map to it (to save me the trouble of bending the image
map before application; see the posting "A Question about Image Maps").

However, if I am understanding the included text (and it is quite possible
that I am not -- I am new at this), the Bend.inc is only used with
animation. Is this right?

If this is correct, a second question suggest itself: What happens if you
animate (bend) an object with an image map on it? Will the image map
distort as the object bends, or bend with it?

Hi. I've never used the bend.inc (only looked at it), so I can't really
answer your second question.
But I see no reason why it shouldn't work with stills. From my short look it
seemed that it simply takes the "to-be-bent" object and cuts it into many
pieces/copies that it puts back together in the bend shape (that right?).
This should work with stills just as fine. And after all, what is an
animation, if not a series of stills...
Now, to your second question again: If my assumption of above is right, then
it might very well work with your image-map problem.

Johannes.

I've used it a few times and Johannes is right, bend.inc just slices up the
object to bend it.  I have used it before with blobs that have different colors,
so I would think it would work with image_maps.  It is difficult to understand
how to use it at first, and it's been awhile for me, so I really couldn't
explain it for you.  The way I learned to use it when I did was by playing with
the included sample scenes.  I remember that once you get into  it, it makes
pretty good sense.  It does have it's limitations, but it comes in handy now and
then.  I did an animation for the irtc called monarch in which I used bend.inc.
You're welcome to look at the source I included with it if you can read it.
