So here's the Houdini project file.

The setup will split and voxel object individually. I also manage to reassign MoI styles back on the 'voxeled' model,
but it only seems to work when using .abc format.
To get the best result, Moi 'divide larger than' meshing option should barely match the voxel grid resolution.

I also use the adaptivity option in the convertvdb operator, to slightly reduce the polycount.
