Hello everyone! Can anyone help me with exporting this animation into an Alembic file? Currently, I can export it so that each sphere in the animation is a separate object. The issue I'm having is that when imported into Blender, the pivot/origin points are not animated; they just stay in place. You can see what I mean in the comment below. Thank you!

Check the hip file for the technique I use. You do have to route the Cd attribute to a material and chose one of the Blender render modes which displays color information. You have to promote Cd to vertex inside Houdini for it to show up in Blender.

Thank you for this solution. It works perfectly. I have one issue with it though: the pivot or origin is not in the correct position. Origins not moving in alembic file. just the surfaces. I've attached how it looks in the FBX file and how it looks here. Is there any solution for this? Thank you for the help so far

Pivot/origins worked only on primitives. (spheres=primitives) but no Cd attrib on export, The convert to polygons is not solved my problem bcs pivot not in normal position.

To fix pivot/origin points not animating in Blender when exporting to an Alembic file, apply all transforms (location, rotation, scale) to all objects before exporting. Check the export settings option for transformations, bake the animation to keyframes for each object's transform, check if objects are parented or grouped in a way that affects pivot points during export, and double-check the settings of custom scripts or plugins for export.
