Linear Workflow
Linear workflow is recommended over gamma workflow to ensure more precise rendering, thus producing more accurate results. Please refer to the linear or gamma workflow manual for more details.
In linear workflow, the preview of all nodes are always displayed in linear color space, except for a few nodes which allow previewing in sRGB, such as the Preview node.
The final output shown in the Game view is shown in sRGB by default, but can be changed to linear as necessary.
