I need to create a powerpoint slide showing an animated 3D model of a conveyor belt. Just like this without the wheels inside...

enter image description here

I wanted to use a cube as the conveyor belt, which I expand to multiple segments using the array modifier.

enter image description here

All segments should then move along a curved path.

Unfortunately, I come to the end of my abilities when trying to implement this animation in Blender. I think I am losing my mind :)

My approach so far has been the following:

Creat the path:

  • Draw a circle and stretch it to an oval
  • Convert the circle to curve

Create the conveyor segments

  • Add a cube and resize it (the mesh should be the conveyor belt)
  • Add Modifier Array to Mesh
  • Enter the number of segments
  • Add Modifier Curve

That's it. If I now select the conveyor belt and move it in Y direction, all segments move along the path.

The tricky part is to get the whole thing to work as an animation in Powerpoint. As far as I know, animations in Blender have to be equipped with an armature, so that the animation works in Powerpoint.

  • Therefore I inserted an armature.
  • Then I select the cube and the armature and press CTRL - P (with Automatic Weights).
  • If I now move the armature in Y direction, the conveyor belt still runs along the path.
  • After inserting the keyframes for the armature I export the file.

But the segments of the conveyor do not move along the path.

What am I doing wrong?

Thanks for the help and best regards Michael :)

  • $\begingroup$ Hi Michael, looks like the inserting of you images didn't work. The easiest way to insert an image to your question is: edit your question, move cursor where you want the image to be and then just paste it in there. (CTRL-V) $\endgroup$

  • $\begingroup$ I have never exported animations to Office products, but as far as I know your assumption of armature requirements is correct. However despite there being an armature in your scene your animation is still based on a curve modifier that bends the shape, and that can't be exported. You will likely need an armature only based animation $\endgroup$ Jun 14, 2021 at 9:57

    $\begingroup$ just a dumb question: why can't you just import the animation in office as a movie file? $\endgroup$
