blender 3.4.1

Is it possible to export this animated cube? I used the Boolean Modifier for the animation. The target format is .glb enter image description here It looks simple but I have tried different variations of these actions: bake animation export to .abc import .abc and export .mdd import .mdd and export .glb and .fbx

No success so far...

.blend file: https://storage.fleek.zone/54c212c3-61ec-458b-aff6-d56851b32e8e-bucket/clear.blend


Error when exporting .mdd---- Exception: Error, number of verts has changed during animation, cannot export

  • $\begingroup$ Unfortunately that's not going to work. Animating a Boolean produces different meshes at different points in the animation, so traditional object export can't support it. $\endgroup$

While the mdd workflow won't work with a boolean, it will work with a shrink-wrap modifier since the geometry is projected to the target and so it is preserved.

When using the shrink wrap modifier use project mode and use a vertex group for the surface you want to follow your target.
