How to implement the pbr map debug mode

JoeyKo · September 20, 2024, 7:10am

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?

          /** Indicates that no code should be generated in the vertex shader. Can be useful in some specific circumstances (like when doing ray marching for eg) */

          @editableInPropertyPage("Generate only fragment code", PropertyTypeForEdition.Boolean, "ADVANCED", {

              notifiers: { rebuild: true, update: true, onValidation: PBRMetallicRoughnessBlock._OnGenerateOnlyFragmentCodeChanged },

          })

          public generateOnlyFragmentCode = false;

          

          /**

           * Defines the material debug mode.

           * It helps seeing only some components of the material while troubleshooting.

           */

          @editableInPropertyPage("Debug mode", PropertyTypeForEdition.List, "DEBUG", {

              notifiers: { update: true },

              options: [

                  { label: "None", value: 0 },

                  // Geometry

                  { label: "Normalized position", value: 1 },

                  { label: "Normals", value: 2 },

                  { label: "Tangents", value: 3 },

                  { label: "Bitangents", value: 4 },

                  { label: "Bump Normals", value: 5 },

                  //{ label: "UV1", value: 6 },

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

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