// 0.01 to 0.99 on the emissivity scale.
// Highly polished metallic surfaces such as copper or aluminum usually have an emissivity below 0.10.
// Roughened or oxidized metallic surfaces will have a much higher emissivity
// (0.6 or greater depending on the surface condition and the amount of oxidation).
// Most flat-finish paints are around 0.90, while human skin and water are about 0.98.

// Emissivity of object
// defaults from app:
// matte		0.9
// half matte	0.8
// half shiny	0.6
// shiny		0.3
