What is the default Vuo lighting model? It looks like a Cook-Torrance/Schlick base model, is that the case?

@George_Toledo, Vuo’s built-in lighting implements the Phong reflection model. The per-pixel, per-light lighting calculation is essentially:

diffuse += dot(normal, incidentLightDirection);  // Lambert
specular += pow(dot(reflection, cameraDirection), specularPower);  // Phong

…with some additional ambient, light-color, surface-color, and attenuation factors.
