Pop up book "folding paper building" Help


Hi all,
Very new to cinema 4d but worked out alot of things to this point. this one is giving me issue though.

I have a popup book scene where a building is situated middle on the paper fold. It needs to fold out and scale up(Y) to 100% as the page opens. So it kind of pops UP as the page is folding out… its a paper house.

At the moment I have just made a left and right parent to each page , basic. but you can see the idea.
Video Example:

Is there a method like a box mesh that is attached to the left and right side (page) and then bends the middle correctly as the page is turning over? Any ideas how to fold a house out and have it pop up like its attached to the page?

So just to recap I need a building to be attached to each side of a opening page and then grow up on the Y while left and right side stay attached in the middle.

Here is the c4d file also.
Made in R25 but opens in R23,24 also. maybe even before them.

1_R_Rotate / 1_joint.R is holding the Right side of the building
1_L_Rotate / 1_joint.L is holding the Left side

there is a full building outside of the parenting called “House_untouched ++++” at the top also.

Thank you ,



This isn’t really a “true” popup, but just a Y growth.

In the example shown, I used PLA.
The middle cube divided in two … outer cubes not divided.
Starting with the last frame … full height …select all top points.
At frame 60, click on record. Move to frame 40 and move those
points down … fully squished cubes … and record.
Now at frame 20, select all left points and rotate axis making sure
to move axis along the X and Y … and record at mid bend stage.
Finally, at frame 0, rotate points to folded position and record.
