Questions tagged [shaders]

A shader is a computer program that is used to do shading, texturing, special effects or post-processing. Shader nodes specifically refer to the nodes used to create shaders for Cycles, but this tag can be used for other shaders as well.

Shaders are most commonly used to produce lighting and shadow in 3D rendering. There are shaders everywhere in blender, e.g. for drawing the 3D view, rendering, etc.

Shader nodes are used in Cycles to define the way light interacts with geometry when rendered.

What does the MixRGB or Mix Shader node factor do exactly?

So on both the mixRGB and the mix shader nodes there is a factor input. But what exactly does the node do? I know that in the case of mix RGB it has something to do with the probability light rays hit either material and that in the case of mix…
