Some of this models have multiple “scenes” that show different animations.

To create your own 3D models with multiple scenes one option is to use Blender and export a GLTF file.

Steps in Blender to create a GLTF file with multiple animations compatible with powerpoint

  1. Create your 3D model
  2. Add armature
  3. Select first the object you want to animate then the armature then ctrl+p then add with automatic weights. That makes the armature a parent to the object.
  4. Change to pose mode, add keyframes for your animation

    Up to here it works with a single animation if you want to have multiple scenes then follow the next steps

  5. Change to nonlinear animation
  6. Push Down Action to create a new track

  7. Move time cursor to beginning
  8. Unclick the track
  9. Repeat steps 3-8 for each new action
