Birth voxels fill the volume up

[tyFlow]

Hmm, yea that's a tricky one. Are you able to verify that there are no overlaps occurring between spheres in the Houdini example? Perhaps Houdini uses a different sphere-packing algorithm rather than simply filling a grid like Birth Voxels in tyFlow...how long does the Houdini example take to generate that many particles (vs Birth Voxels, on your machine)?

tyFlow's Birth Voxels operator uses a grid-based approach to scatter particles, which can result in visible patterns...adding jitter can remove the patterns but then gaps can be created, as you can see.

More info about the Houdini approach would help me figure out if it's something I can integrate in tyFlow.
