Octane Light Pass ID Mask
Posted: Thu Sep 03, 2026 7:21 am
There is a UI inconsistency regarding Light Pass IDs between the light properties and the Kernel settings.
In the OCTANE_Light properties (Render tab), the Light Pass ID parameter allows selecting up to 20 Light Pass IDs. However, in the Octane Mask node (Render Target / Kernel settings), the node interface only displays buttons up to Light Pass 8.
Because of this, any light assigned to a Light Pass ID above 8 cannot be masked or toggled via the Octane Mask node.
Expected Behavior:
The Octane Mask node should include buttons/toggles for Light Pass 9 through Light Pass 20 to match the core engine's capabilities.
