SurfaceAppearance
SurfaceAppearance objects let you override the appearance of a MeshPart with advanced graphics options. Most notably, it can apply a set of Physically‑Based Rendering (PBR) texture images, or maps, on a single object. Combining multiple texture maps can more accurately simulate color, roughness, and reflectivity in any lighting environment and can enhance the visual elements of your assets and environment; see PBR Textures for more details.
Appearance of this object on a MeshPart depends on the user's device and graphics quality level. For best results, you may want to preview your content with different quality level settings.
Note that most SurfaceAppearance properties cannot be modified by scripts, as the necessary pre-processing is usually too expensive during runtime.
