Important, additional explanation about URP & HDRP

I found that Unity3D has integrated debugging capabilities. Open Window -> Analysis -> Rendering Debugger Rendering Debugger Window -> sidebar:Material -> Material Filters Dorpdown material override or vertex attribute select the item you want to debug.

CustomDrawMode

This is a simple tool designed for technical artists. It extends and customizes the Draw Mode of the Unity3D Scene window.

You can view a model's base color, metallic, smoothness, roughness, ambient occlusion (AO), normals, emissive, vertex colors, grayscale, UV0, and UV1 in the Scene viewport.

The tool supports both the built-in rendering pipeline and the Universal Render Pipeline (URP).
