-/**
- * The aim of this mesh material is to use information from a post processing pass in the diffuse color pass.
- * This material is based on the MeshPhysicalMaterial.
- *
- * In the current state, only the information of a screen space AO pass can be used in the material.
- * Actually, the output of any screen space AO (SSAO, GTAO) can be used,
- * as it is only necessary to provide the AO in one color channel of a texture,
- * however the AO pass must be rendered prior to the color pass,
- * which makes the post-processing pass somewhat of a pre-processing pass.
- * Fot this purpose a new map (`aoPassMap`) is added to the material.
- * The value of the map is used the same way as the `aoMap` value.
- *
- * Motivation to use the outputs AO pass directly in the material:
- * The incident light of a fragment is composed of ambient light, direct light and indirect light
- * Ambient Occlusion only occludes ambient light and environment light, but not direct light.
- * Direct light is only occluded by geometry that casts shadows.
- * And of course the emitted light should not be darkened by ambient occlusion either.
- * This cannot be achieved if the AO post processing pass is simply blended with the diffuse render pass.
- *
- * Further extension work might be to use the output of an SSR pass or an HBIL pass from a previous frame.
- * This would then create the possibility of SSR and IR depending on material properties such as `roughness`, `metalness` and `reflectivity`.
- *
- * @augments MeshPhysicalMaterial
- * @three_import import { MeshPostProcessingMaterial } from 'three/addons/materials/MeshPostProcessingMaterial.js';
