As of Unity 2021.2, Shader Graph added a Built-In target.
Shader Graph is only compatible with Universal Rendering Pipeline (formerly LWRP), and High Definition Rendering Pipeline.
The built-in render pipeline does not support Shader Graph.
- Switch render pipelines to use Shader Graph. This is generally advisable at the start of a project with an understanding of the repercussions associated with using one.
- Switch to URP.
A light-weight pipeline set to replace the Built-in Renderer.
- Switch to HDRP.
A complex high-fidelity pipeline intended for modern PCs and Consoles.
- Use an alternate solution.
- Update your project to Unity 2021.2+, and update Shader Graph to
12.0.0+ to support built-in.
