Description:

Light/shadow linking - controls which objects a light illuminates or casts shadows onto. Cycles only. Mirrors Blender's own model 1:1: the type picks which slot on the emitter is managed, the mode is the per-member link state inside the managed collection.

Properties:

• Linking Type
  • Light - manages the light's receiver collection.
  • Shadow - manages the blocker collection (what casts this light's shadows).
  • Both - both slots, each from its own input.
• Mode
  • Include - members' link state = INCLUDE (only they receive light / block shadow).
  • Exclude - members' link state = EXCLUDE (everything except them).

<aside> ⚠️

Flipping the mode and re-building the graph flips member states in place - membership never changes with the mode.

</aside>

• Name - base name for this node's managed collections:<name>_recv and/or <name>_cast. Empty = the first matched light's name.
