Optional options: MToonMaterialLoaderPluginOptionsPrivate _addPrivate _extendPrivate _generateThe target mesh
Private _getMToonPrivate Readonly _mLoaded materials will be stored in this set.
Will be transferred into gltf.userData.vrmMToonMaterials in afterRoot.
Private _parsePrivate _removeDelete use of KHR_materials_unlit from its materials if the material is using MToon.
Since GLTFLoader have so many hardcoded procedure related to KHR_materials_unlit
we have to delete the extension before we start to parse the glTF.
Private _setupThis will do two processes that is required to render MToon properly.
A target GLTF primitive
The material index of the primitive
Debug mode for the material. You can visualize several components for diagnosis using debug mode.
Readonly parserThis value will be added to renderOrder of every meshes who have MaterialsMToon.
The final renderOrder will be sum of this renderOrderOffset and renderQueueOffsetNumber for each materials.
0 by default.
There is a line of the shader called "comment out if you want to PBR absolutely" in VRM0.0 MToon.
When this is true, the material enables the line to make it compatible with the legacy rendering of VRM.
Usually not recommended to turn this on.
false by default.

Generate outline for the given mesh, if it needs.
