Hey Brandon, I'm trying to achieve the same thing, and export the point cloud into a PLY model (using the same sample project). I am very new to ARKit, and I couldn't figure out exactly how to do so by reading this thread. You mentioned that you have achieved this in your last comment. I was wondering if you could provide a bit more detail on the implementation. In particular, how did you end up saving the data from the particlesBuffer into a PLY model?
