I would like to convert my ball model into a 2d-ish model with an animation. Already tried to find some tutorials or materials presenting ways to do that, without success.

Ball model

I would like to animate the ball into something like this:

Target representation

I believe this is a hard thing to do, specially cause I don't have too much experience with Blender (started to model with 3Ds max) or animation, but I would like to try even so. Any ideas or tutorials?

  • @vklidu thank you sir, I'll check it out the script, hopefully I'll be able to achieve what I want. – Gabriel Minosso Dec 19 '19 at 01:41
  • @vklidu Got this error when tried to activate the convert to armature addon in the Blender 2.79b:

    Not sure why it's happening, already look in the tool's page but didn't find anyone with this particular error...

If you are looking for result like in your second image - ready to use file (print-cut-glue), use build in "Paper Model Export" addon by Emu.

But for unfolding, use his "Convert to Armature" addon - download version for 2.8x. More info here.

Unfold Animation

  • download-install-enable addon
  • select object, go to edit mode (Tab), select edges you want split
  • Ctr+E > Mark Seam
  • search Split Seams
  • additionally select one face you prefer to start generate bone tree
  • search Convert to Armature

That's all ... to be precise, object is not animated yet. Script generates Armature object with bones assigned to faces and creates unfolded Pose. To animate unfolding - go to Pose Mode (Ctrl+Tab), select all bones, add Keyframe (I) > Rotation, move on Timeline, Clear Rotation (Alt+R), add second Keyframe > Rotation.

enter image description here

If you have more complex mesh you can let "Export Paper Model" script to Mark Seams for you (3Dview > Properties Panel (N) > Paper > Unfold). Continue as described above - search Split Seams ...

I did not test it but I think it's worth a try.

Try TexTools addon. It makes an animation using the UV Mesh and the mesh using Shape keys.

  • Thanks @LeoNas, I would like to keep the 3D aspect of the ball parts after the animation. But this seems useful indeed, I'll check it out and use it as a prototype at least, if the result is good, I'll stick to it. – Gabriel Minosso Dec 19 '19 at 13:28
