Root Cause

The material or shader is designed for URP but the project is using Built-in Render Pipeline, or vice versa.

中文

材质或着色器是为URP设计的，但项目使用的是内置渲染管线，反之亦然。

Workarounds

  1. 95% success Convert the project to URP via Window > Render Pipeline > Universal Render Pipeline > Upgrade Project Materials to URP Materials, or manually assign a URP-compatible shader like 'Universal Render Pipeline/Lit'. 
    Convert the project to URP via Window > Render Pipeline > Universal Render Pipeline > Upgrade Project Materials to URP Materials, or manually assign a URP-compatible shader like 'Universal Render Pipeline/Lit'.
  2. 90% success If staying on Built-in RP, replace the material's shader with a Built-in equivalent like 'Standard' via the material inspector.

中文步骤

  1. 通过Window > Render Pipeline > Universal Render Pipeline > Upgrade Project Materials to URP Materials将项目转换为URP，或手动分配URP兼容的着色器，如'Universal Render Pipeline/Lit'。
  2. 如果保留在内置渲染管线上，通过材质检查器将材质的着色器替换为内置等效项，如'Standard'。

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Simply changing the shader name in the material inspector does not update the underlying shader code; it may still reference URP-specific functions.

  2. 70% fail

    Deleting and re-importing the shader file does not fix the pipeline incompatibility; the shader must be rewritten for the correct pipeline.
