Description:

Create or assign a Cycles light group for the filtered lights. Light groups live in two places in Blender, and the node manages both: per-object membership, and the per-view-layer registry that makes the group render as a pass.

Properties:

• Mode
  • Assign - assign an existing group, chosen via the picker. It scans groups registered on the scene's view layers, groups already assigned on objects, and virtual ones pending in the graph (Layer Settings entries, other Create-mode Light Group nodes).
  • Create - create a new group, register it per Register On, and assign it to the matched lights.
• Group Name - the group name: picked in Assign, typed in Create.
• Register On (dropdown)
  • All View Layers - register the new group on every view layer.
  • Active View Layer - register on the currently active layer only.

Usage Notes:

• Registration is additive - existing groups are never removed, and re-applying changes nothing.
