Feature

The KHR_materials_specular extension adds parameters to the metallic-roughness PBR model, allowing users to configure the strength and color of the specular reflection in the dielectric BRDF.

CesiumJS does not recognize these parameters in a glTF. Here is how the sample model is currently rendered. Note how all the spheres appear the same.

Compare to the result from the reference implementation with the extension enabled:
