A Shader Graph does not need a Material to be applied to a Scene or a GameObject.

A Shader Graph indeed requires a Material to be applied to a Scene or GameObject. In Unity, a Shader Graph is a visual tool for creating shaders, which define how surfaces render in terms of lighting, texture, and other properties. However, shaders themselves are not directly applied to GameObjects; they must be encapsulated within a Material first.

When you create a Shader Graph, you design the shader’s visual effects and properties. Once the Shader Graph is complete, you need to create a Material that uses that Shader. This Material is then assigned to a GameObject or used in a Scene, enabling the visual effects defined in the Shader Graph to take effect on that object. Without a Material, the shader cannot be utilized, making the statement that a Shader Graph does not need a Material incorrect.
