GBuffer To Image

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.

Attributes

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

Outputs

Outputs an image or video that can be connected to any relevant video input, most commonly an Image 2D node.
