Hi Max,
Sadly my temp X-Particles version has run out of time. So, I’m trying a blind folded flight here.
There is certainly an option to create a little geo-representation for each particle in X-Particles. This would be then needed to be exported as “.obj” based sequence.
Since X-Particles can feed Thinking Particles to my knowledge, you could feed the visible particles into a PShape node. With a “Particles Geometry” group, this would create the geometry you ask for.
I have send an e-mail to INSYDIUM LTD, asking for a student version. I zero budget to buy all that things connected to Cinema 4D, and that is a lot. Typically the industry is supporting my efforts with NFR versions. We will see how it goes.
All the best
