WebAug 16, 2012 · Did some testing using the FormFonts tester ball to compare the 3 shaders and their affect on render time. Phong seems to render faster and blur reflections a bit less. Ward, from what I am told, is good for metals but render times are much longer. Blinn seems to be good for materials where you want really blurry reflections.

WebReflection Occlusion (Phong, Blinn, Ward) – Reflection occlusion is used. The difference between ambient and reflection occlusion is basically in the direction in which rays are traced. With ambient occlusion, rays are traced in all directions uniformly, whereas with reflection occlusion, the direction depends on the viewing direction (just ... WebUsing V-Ray and the V-Ray Material, you have the choice to use Blinn, Phong or Ward for the BRDF ( Bidirectional reflectance distribution function) parameter for the material, which is what describes how light is reflected off the surface of the material – or how the specular highlight component of the material looks when rendered.

WebJan 7, 2009 · From what I've seen, people often use Ward for metals, and Blinn/Phong for plastics.
