The material tag is stacked over the base material.
In this case, the Corona Distance Shader is feeding the Opacity channel. Wear and tear on objects which are close to each other:Ī Noise map is used to vary the distance scale, producing the " rust" effect. Here are only a few example ideas, that can be developed further: The Corona Distance Shader is extremely versatile and can be used in various cases, depending on the needs. CoronaDistance is computed in one go, and will immediately render noise-free.
Corona Distance can be used in such cases, and it will update in real-time, even in the viewport. This means that the Corona AO Shader cannot be used, for example, as a distribution map to scatter instances using a Cloner object, as a displacement map, or as a bump map. Corona AO is raytraced, so it is computed only during the actual rendering.The Corona Distance map can only be used based on the distance between two or more different objects. Corona Distance Shader cannot be used within a single object.Ĭorona AO Shader can be used to color different parts of a single object or multiple objects based on their distance from each other (convex or concave areas).How is it any different from Corona AO Shader? The Corona Distance Shader can be used with both 2D textures (such as bitmaps or procedural maps on the object surface) and 3D volumes (such as objects using the Corona Volume material). These colors can be then mapped to various material or object properties such as opacity, displacement, or scattering distribution, or can be used as masks, just like any other map. The Corona Distance Shader applies different colors to a material based on the distance from one object to another. Use this to add waves around a coastline, wear-and-tear where objects meet, dirt and noise under window sills, and more. The Corona Distance Shader lets you create "smart" materials that know how far away they are from objects in the scene. Solution home FAQ - C4D FAQ - Materials and shaders Corona Distance Shader - C4D
