The Root node for the scene.
Root
Method #
The Root node for the scene, controlling the basic scene setup and other important global scene attributes. All subsequent nodes in the Notch Project should be connected to the root to exist and contribute to the scene, either directly or indirectly.

Parameters
Parameter Details Preview In Viewport Preview the generated image as an overlay in the viewport.
- Off : No preview is generated.
- RGBA : Preview the image blended with alpha in the viewport.
- RGB : Preview the colour channels in the viewport.
- Alpha : Preview the alpha channel in the viewport.
Composition Colour Control the colour of the composition in the Notch UI.
Background Colour Set the background colour for the project. Does not affect lighting, but may appear in reflections.
Current Camera Select which camera is currently being used in the scene. This won’t affect the rendererd output, which will still use the Current Playing Camera.
Dither Output Dithers the Final image, breaking up any visible banding in the scene.
Colour Space Control the working colour space in Builder. For more on using Colour Spaces in Notch, see our page on Colour Management.
Composite Blend Mode Change how this composition will blend with other compositions in the project. See Blend Modes for details.
Composition Alpha Control the oveerall alpha of the composition.
Output Premultiplied Alpha The final RGB colour values are multiplied against the Alpha value before being output. Useful for cleaner blends regardless of whether alpha transparency is used.
Output Render Layers Side By Side Split the output render into a left and right side, where Render Layers can be selected to render to either side. Nodes connected directly to the Root will default to the left side. Useful for Virtual Productions workflows, to split the output between front and back plates.
- No - Output Composite : Don’t split the output.
- Output Side By Side : The viewport will be split in two, with the front and back plates on either side.
- Output Left Only : Only shows the back plate.
- Output Right Only : Only shows the front plate.
Flip All Polygon Culling Flips the direction of back face culling for 3d objects are connected to the Root node.
Offscreen Render Target A screen resource to which the contents of the compositions’s final render will be copied to after rendering, for use as a texture in future compositions.
These properties controls simple metadata for the composition.
Parameter Details Creators Contains the name of the original creator(s) of the scene.
Project Version Stores the current project version this file was last saved in. Useful for debugging.
