Octane PBR V 3.08 RC3 BRDF Model "Beckmann" for glossy nodes Example KONTEXT Beckmann, GGX, Ward: These types are functions that only differ in the manner with which they uniformly weaken reflections from the ideal reflection angle ( = angle of incidence). This can occur slower/faster or stronger/weaker. Basically only variations of Type a and b shown above. If you take a look at the different depictions you will see that the differences are only very slight. Beckmann is a physically correct and fast type and should therefore be the preferred method for normal use. GGX produces the greatest dispersion and works best for simulating metal surfaces a bright specular highlight with diminishing brightness. Ward is best suited for soft surfaces such as rubber or skin. DarkTide Character by W.Vaughan 2017
