Emits photons onto a scene based on surface characteristics, such as diffusion, reflection, and transparency. You can manipulate photon properties such as specular color, refraction, etc. This tool shader is used to create caustics.
This shader is connected to the Photon input of the Material Node Without This shader (or a surface connection in the Photon input), caustics and global illumination effects will not render. Instead of defining a color, you can also connect a texture to either the Diffuse, Specular or Transparency inputs.
Placing another shader (such as a Color Correction shader) between the Material Node and this shader will nullify any photon effect. This shader can be anywhere in a render tree effect as long as the shader it is attached to is also attached to the Photon input of the material node.
