Emissive#
Emissivity defines how much light a surface emits independently of received light. This parameter creates self-illuminating effects like neon signs, screens, or bioluminescence materials. Emissivity maintains physical accuracy by contributing to scene lighting and global illumination calculations.

Enable Emission
Toggles light emission from the material surface
Emissive Color
Specifies the color of emitted light
Emission Color: .94, .89, .65# |
Emissive Color Map
Accepts a texture file to define emission color values.

Emissive Map Color Space
Valid Texture Gamma Values
raw : Use texture data as it was read from the texture and do not mark it as using a specific color space.
sRGB : Mark texture as sRGB when reading.
auto : Check for gamma/color space metadata in the texture file itself; if metadata is indicative of sRGB, mark texture as sRGB. If no relevant metadata is found, mark texture as sRGB if it is either 8-bit and has 3 channels or if it is 8-bit and has 4 channels. Otherwise, do not mark texture as sRGB and use texture data as it was read from the texture.
Emissive Mask Map
Accepts a texture file to define emission mask values.

sRGB : Mark texture as sRGB when reading.

Emissive Intensity
Determines the intensity of emitted light.
