LuxCoreRender Textures Spectrum
Spectrum Texture Types
Blackbody
- Output value: color
By indicating a color temperature, LuxCoreRender will use the spectral distribution of a blackbody. This is useful for for example light bulbs (2800-3300K), candles (1850K) and the sun (5000-6500K). For a detailed explanation, see for example techmind.org
Color Depth
- Output value: color
Color depth, also known as color at depth, is a texture designed to make setting absorption simpler. Normally, you set absorption by defining the color that will be absorbed, resulting in a color control that is essentially "backwards". This texture allows you to instead set the desired result color and how far the light should penetrate before reaching that color.
Parameters
- Transmission color - The target color of the transmitted light as it reaches the defined depth
- Depth - The depth at which the specified transmission color is reached
