I am wondering how to make a cube squish like a sphere on the Z axis. It will be an animated cube, so it needs to squish like a real sphere.

  • $\begingroup$ Are you asking specifically about how to do it in Blender, or about animation in general? $\endgroup$ – Matt Dec 3 '13 at 23:24

  • $\begingroup$ I am asking how to make it squish like a sphere in blender. If you went into blender, brought out a cube and squished it down on the Z axis, you will see that the results are different than a sphere. My question is how can I make it squish like a sphere in blender. $\endgroup$ – Joshua Slink Dec 3 '13 at 23:30
  • $\begingroup$ If you go into the scale manipulatior and scale a sphere down on the z axis it will squish like a bouncy ball would squish. That is the effect I am trying to acheive. $\endgroup$ – Joshua Slink Dec 3 '13 at 23:32

You can quickly achieve this with a Simple Deform modifier set to Stretch and using a negative Deform factor.

  • $\begingroup$ A more efficient way could be to make a simple one bone rig and use some shapekeys but this works. $\endgroup$ – iKlsR Dec 3 '13 at 23:51
  • $\begingroup$ Thank you. I just have a few questions about it. If you could just give me the steps that would be great. $\endgroup$ – Joshua Slink Dec 4 '13 at 0:01
  • $\begingroup$ @JoshuaSlink The steps are in the answer ;). Just add a cube, subdivide it a couple times, add the modifier to the cube, set it to Stretch as seen in the image and use a negative deform factor, you can then keyframe this and adjust the influence etc. $\endgroup$ – iKlsR Dec 4 '13 at 0:03
  • $\begingroup$ When I use the negative deform factor, it does not look like yours at all. Do you know why? $\endgroup$ – Joshua Slink Dec 4 '13 at 0:07
