Hey, guys.

In the babylonjs inspector, we can check pbr map in debug mode.

As we found the source code has many debug mode values, Is there any ways to implement these debug mode values in the project?

Hi~, if you want to make a PBR material to show with debug mode, you can set material.debugMode directly.  
Like this PG:

> **[Babylon.js Playground](https://playground.babylonjs.com/#UIITSU)**

if you want to show as Normals Mode, you can set debugMode with 2
