Method
This node allows GBuffer channels from a rendered scene to be used as video nodes for compositing or export purposes. By default, the base render layer is used as the GBuffer source, but a Render Layer may be supplied via appropriate input.
For most channels to be accessible, Deferred Rendering must be enabled in the root node.
*Use a Video Exporter node to export the contents of the GBuffer To Image node to video. Multiple channels may be exported separately and simultaneously.

|
| Normal – Local Space |
The normals of all surfaces in the scene, relative to the camera. |
![]() |
| Specular Colour |
The colour of specular lighting on all surfaces in the scene. |
|
| Depth – Camera Space |
The depth of all surfaces in the scene away from the camera, without compensating for the camera far plane. |
|
| Depth – Camera Space (Normalised) |
The depth of all surfaces in the scene away from the camera, compensating for the camera far plane. |
![]() |
| World Position |
The position of each point in the scene in world space. |
|
| Object mask |
Uses geometry to mask all surfaces in the scene. |
![]() |

Colours objects using their internal Object ID’s. |
|
| Material ID |
Colours objects using their internal Material ID’s. |
|
| Object ID (False Colours) |
