Hello, long time Houdini user, still feel like I haven't scratched the surface, first forum post. The issue I'm having seems super pedestrian, but I can't seem to beat it.

ISSUE
I have built a particle system where I'm copy-stamping sphere primitives to the particles in order to have a bubble-ish look. I need to get this scene out of Houdini now and into Cinema4D for fresh lighting and rendering, ideally Alembic.

I have tried FBXing, but it turns the thousands of primitives into extremely heavy geometry. I was thinking perhaps I could save out the points with their changing scale attributes or something so he could copy C4D primitives to them, but I really haven't been down a road like this before.

BACKSTORY
(I had previously rendered it out, got it final'd, but now the lighting art direction has changed and I am already on another project.. the next artist only knows how to render out of Cinema4D, and if I can't somehow give him what I built, it's going to have to be built again from scratch, basically scrapping all the work I put into it.)

Any Ideas?
I have attached 24 frames of a stripped down version of the geometry I'm having trouble exporting. Any advice appreciated.
