Mesh Emitters

Mesh emitters let objects act as light sources. To use a mesh as a light source, the light source needs to be either a DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters., Standard Surface, or Universal material type. The emission types can be connected to the material's Emission input (figure 1)

There are two types of EmissionsThe process by which a Black body or Texture is used to emit light from a surface.:

• Blackbody Emission - Uses Temperature (in Kelvin) and Power to control the light's color and intensity.
• Texture Emission - Lets any valid Texture type to set the light's intensity. This creates effects, such as TV screens, by using an Image texture as the source.
