The problem is to get the smooth natural animation of folding over say a piece of paper, where it starts flat and forms a natural curve. Would bones do that?

[johnar]

 You can use morphs and bones at the same time. Above is bones only, but morphs could also be added to do things like 'have the breeze created to blow/curve the edge slightly as it closes, .

 Could be improved, but hopefully you get the idea.

You are right. much nicer. I'm missing something on Morph. I can duplicate RudySchneider's Morph example. But we need an endpoint image as a template to know where to drag the points to. 
How did you get the curves in the paper as your example shows?
Thank You.

 I've attached the an8 file (zip) at the bottom.
Front view -> object edit mode -> wireframe view
 Drag selected the last 4 rows of points and moved downwards, (Y), incrementally, so that the 1st outside edge was the lowest, 2nd edge slightly higher and so on, as you'll see in the file. (build -> morph targets -> fold
 Then, check out the keyframes in scene mode.
 Also, check out the figure in fig mode
 Hopefully that will all make some sense.
  I name my morphs slightly differently than RudySchneider, but obviously, either way will work.
 The way i set my morphs is probably best explained by this old vid.

hi johnar took a look at your elegant solution to folding paper.All these years using anim8or and i never realised i didn't necessarily need to create and import a sequence to make a boned figure animate.

...How did you get the curves in the paper as your example shows?

Make sure your paper has enough divisions, and use a "string" of bones.  Consider your fingers.  They don't simply fold flat; they "roll" closed into a fist because each joint adds another bend to the sequence.

WOW Johnar, the video was IMPRESSIVE! Even though I though I knew what to do, there were a lot of details here, as they say:)- "picture worth 1024 (2^10) words".

You moved all the points by eye. Is there a way to create a template or underlay of the desired final morph and drag the points to that? Then remove the template.

Thank You.

s there a way to create a template or underlay of the desired final morph and drag the points to that? Then remove the template.

That would be 'reference images'.
 Object mode -> build -> reference image.

RudySchneider Happy new year. Long time no hear from. Yip, the method you describe is another effective way to 'bend' things. Take note Owl.

captaindrewi Its funny how we find a way to do something, then stick with that until one day, out of the blue, find something that makes us re-evaluate how we've been doing it till then.
 I went straight from 'total computer newbie' to Anim8or, and spent the first couple of years 'dragging anim8or out to fill my screen'. Then one day a friend said to me 'just double click in the blue area along the top'.  Lol.  Man, did i feel silly, but then, what a great day that was.
