| # MandarinOrange | ||
|
|
||
| ## Screenshot | ||
|
|
||
|  | ||
| _Screenshot from the development version of the [glTF Sample Viewer](https://gltf.ux3d.io/) which supports KHR_materials_diffuse_transmission._ | ||
|
|
||
| ## Description | ||
|
|
||
| This asset is a test of the glTF extension [`KHR_materials_diffuse_transmission`](https://github.com/KhronosGroup/glTF/pull/1825) to demonstrate the scattering of light through the fruit of the orange. | ||
|
|
||
|  | ||
| _Two screenshots, with KHR_materials_diffuse_transmission (left) versus without._ | ||
|
|
||
|  | ||
| _The textures. Top row from left: base color, occlusion, roughness. Bottom row from left: normal, diffuse transmission factor, diffuse transmission color._ | ||
|
|
||
| The original model on Sketchfab from zandreamer is a photogrammetry asset which only contains a base color texture. All the additional textures were created by processing the base color through a series of filters in various art tools. | ||
