Hi, everyone! I’m trying to make a book animation and I’ve faced with some troubles because of overlapping pages.

The method I used was, in first place, animate a plane with bend deformer, then clone this animation and applied step effector to separate pages across time. But the pages always overlap when finished each animation. I’ve tried to change the clone parameters in Y amount but didn’t work. (I think the problem is in Cloner)

So my question is, anybody know how to solve this?

Finally, about texturing, exist a way to apply different textures in page faces?

I attached in this link the scene files I’m talking about: https://app.box.com/s/ezhofhqju58mqsaec0za

Thanks for your time, and hope you can help me.

Hi IAEC,

The idea, in the attached file is based on “magic”. In other words, what the eye can’t see, will support the illusion.

More than often we have in 3D more options than in reality.

To shift pages from right to left and change the order from top to down—can be done in two steps in an much easier way.

For that I introduced half the way of the page flip an sudden scale to zero. I copied the set up and in the copy I changed the scale from zero to one exactly in at the same frames.

Have a look, you might see it (or not, if it works ;o)

The Cloth-Surface will not support two sides if “thickness” is anything other than zero. ..or you duplicate the whole set up and have one time + and one time - for the thickness, with a different material, etc…sounds complex, but possible. The Y value in the Cloner Object has to agree somehow with that.

I have set up the pages now with two materials, one time (Texture Tag>Tag>Side>) front and one time back.  So one time has the even page numbers one the odd numbers, if I’m not mistaken.

You could also set up the pages like a thin “cube” and use selections for that. Select one area and place it into the Texture Tag>Tag>Selections. This would allow for a white side/border on the page.

The check the Y values for the Cloner, clones and Object Pos.

All the best

P.S.: I had to test the double Cloth Surface idea.

Have a look to the example. Just to guess was not really my ideal. :o)

Hi Dr. Sassi! Thanks for the advice, it works fine. Definitely I used the pages without cloth surface. ( I attach the scene file with the result: https://app.box.com/s/6a7yagt7spfq2xoklrhl) What I noticed is if I increment the value in the time offset in the step effector it appears a kind of drop in flip animation and if I reduce it, this drop disappears. Why is that?

Other thing, I created a very very rudimentary cover to animated. I think there should be a more efficient way to do it. I was thinking in animate a spline with joints and then extrude it, to create the cover in one single piece that can be animated. Is an efficient way to do it? I’m going to try and then post the result if it works.

Thanks a lot for your time and suggestions Dr. Sassi!

Regards!

Hi iaec,

The “drop-outs” after the a change of time - so far I can tell for this set up might occur in two ways. One time if you change the timing in the middle of the scene (time wise) and press then play. This should be not repeatable for a second run while no further changes have been made.

The other time I though I spotted something like that, were based on that I have stretched just all Keyframes as a group. As a result, the critical scale change from one frame to the next was stretched as well. Perhaps I should have set up there a “step-Interpolation”, but this change creates the “magic”, so it is critical that this is adjusted accordingly. The Time offset in the Step-Effector will alter this “scale change/time” as well, so it needs to be done carefully.

Brainstorming: Perhaps you try the Mesh Deformer. Low polygons, and then apply this to the hi res model. Pose Morph comes to mind or simple deformers. There was a book cover tutorial a while ago, but I can’t find it.

All the best

P.S.: Here is a very rough sketch, following up on your idea about the book cover. I tried to find the most simple set-up possible.

You can create a hierarchy with the Nulls (move them with the L key down, to not affect the others, certainly something you know, but just in case)

Again—this is more than a rough sketch, with the emphasis on “rough”. But I think you get the idea. Rotate the parent Nulls.0-2 or the top one. In the front view or R.B only!
