Instance Separator

The new mayatk.core_utils.instance_separator.InstanceSeparator class wraps the payload discovery logic that powers the auto instancer. It lets you inspect a selection (or a supplied node list) and understand which meshes can be instanced before you modify the scene.

from mayatk.core_utils import InstanceSeparator

separator = InstanceSeparator(
	tolerance=0.99,
	require_same_material=False,
	split_shells=True,  # auto-separate multi-shell meshes
	rebuild_instances=True,
	template_position_tolerance=0.25,
	template_rotation_tolerance=7.5,
)
result = separator.separate()  # Uses the current Maya selection by default

for group in result.instantiable_groups:
	print(
		f"Prototype {group.prototype.transform} has {len(group.members)} duplicates"
	)

for assembly_group in result.instantiable_assembly_groups:
	print(
		f"Assembly {assembly_group.prototype.source_transform} has {len(assembly_group.members)} duplicates"
	)

Feed the result.groups back into AutoInstancer (or your own tool) to carry out the actual instancing, or let InstanceSeparator rebuild duplicate assemblies directly (enabled by default). Use result.unique_groups or result.unique_assemblies to flag geometry that still needs manual cleanup. Tune template_position_tolerance / template_rotation_tolerance if parts sit farther apart or have mirrored orientations.
