When this mode is selected, the rays are traced inside the surface, instead of outside the surface. ![]() This mode changes the tracing direction of the rays. instead of crevices, open corners are shaded with the occluded color. ![]() Inner occlusion – Allows the user to invert the effect with respect to surface normals - e.g. With Ambient occlusion rays are traced in all directions uniformly, while with Reflection occlusion the direction depends on the viewing angle(just as when calculating reflections) and the spread of the rays depends on the Reflection glossiness and BRDF type used. The difference between ambient and reflection occlusion is in the direction in which rays are traced. Reflection occlusion (Phong, Blinn, Ward) – Reflection occlusion is used. Occlusion Mode – Specifies the mode in which the dirt map is going to be calculated.Īmbient occlusion – Normal ambient occlusion is calculated.
