Detailed Description¶

class Kuesa::Qt3D;

Kuesa::Qt3D::ClearCoatMetallicRoughnessMaterialExtension extends the default physically based rendering (PBR) material based on the glTF 2.0 material description with support for the KHR_materials_clearcoat extension.

See:

Since: Kuesa 2.1

Note: ClearCoatMetallicRoughnessMaterialExtension's behavior is implemented using a custom shader graph and layers on the MetallicRoughnessEffect. Some changes in the properties will activate or deactivate some nodes of the shader graph and will trigger a recompilation of the shader. It is recommended to create the variations of the material that you need once up front at application initialisation time.

It is configured through the set of properties held on the ClearCoatProperties instances it can receive.
