This model demonstrates the usage of KHR_materials_sheen, KHR_materials_transmission and KHR_materials_clearcoat.
This model also includes eight sample cameras, featuring different angles on the car and its materials. In software packages that represent camera locations with 3D markers, it may be beneficial to reduce the size of these markers, as marker size is not specified in glTF.
