The VDB to Particles operator can be used to convert VDB meshes into particles.
Mesh to Particle: converts any generated VDB meshes into a single particle.
Pack mesh with particles: packs any generated VDB meshes with particles.
Max particles: the maximum number of particles to pack the VDB mesh with.
Min/max radius: radial constraints applied to generated particles.
Samples: the number of samples to use in the packing algorithm. Higher values increase packing accuracy.
Allow overlap: when enabled, resulting particles are allowed to overlap. When disabled, no generated particles will overlap.
Assign unique ID: when enabled, each iteration of the sphere packing algorithm will assign a unique ID to the resulting particles.
Channel: the name of the custom float data channel where the unique ID will be assigned.
