Implementing a simple Shader Graph
In Unity, GameObjects gain functionality through components. Every GameObject includes a Transform component, and additional built-in or custom components (via MonoBehaviour scripts) define behavior and appearance. Renderers determine an object’s visual representation, with MeshRenderer being common for 3D models. While an object typically has one renderer, it can contain multiple materials, each wrapping a shader—the core element in 3D rendering.
With Shader Graph, creating shaders is more intuitive, allowing visual shader development without coding. This tool is particularly useful for projects using URP or the High-Definition Render Pipeline (HDRP).
The relationship between shaders, models, materials, and objects can be illustrated as follows:
