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.
Attributes
| Name | Description |
|---|---|
| Preview In Viewport | Preview the effect blended with alpha in the viewport. |
| Preview RGB In Viewport | Preview the RGB values in the viewport. |
| Preview Alpha In Viewport | Preview the alpha values in the viewport. |
| Source Channel | This selects which channel from the Gbuffer to generate as an image. |
| Channel | Description | Reference image |
|---|---|---|
| Composite Colour | The composited output from the viewport. |  |
| Colour | The unshaded colour of all objects in the scene. |  |
| Alpha | The Alpha channel of the scene. As its a Gbuffer output, only alpha from geometry will be accepted (e.g Shadow Catcher), not the full layer alpha. |  |
| Normal – World Space | The normals of all surfaces in the scene, relative to the world. | |
| 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. |  |
| Object ID | Colours objects using their internal Object ID’s. | |
| Material ID | Colours objects using their internal Material ID’s. | |
| Object ID (False Colours) | Colours objects using their internal Object ID’s – but with false colours to make differences more obvious. | |
| Material ID (False Colours) | Colours objects using their internal Material ID’s – but with false colours to make differences more obvious. |  |
| Roughness | Colours Objects using the different values of roughness on object surfaces. |  |
| Metallicness | Colours Objects using the different values of metallicness on object surfaces. |  |

Inputs
| Name | Description | Typical Node Input |
|---|---|---|
| Render Layer | Use the gbuffer of a specific render layer. | Render Layer |
| Effect Mask | Mask out areas the effect wont affect the image. | Image Plane |
| Alpha Image | Add an image to control the alpha values of the image. | Video Loader |
Outputs
Outputs an image or video that can be connected to any relevant video input, most commonly an Image 2D node.
