"Material" settings on an object effectively control how light interacts and reflects off of said object.

For example, material settings can be used to make an object look reflective (light bounces off), look like glass (light goes through), look like chalk (light is very diffused at the microscopic level), or other such interactions.

== Property Values ==
* '''Base Color''' - The underlying/overall color of a material.
* '''Subsurface''' - Allows light to enter the object, bounce inside it, and reflect back out. 0 leads to a more plastic-like look. 1 gives a more waxy look. Note that subsurface is also important for flesh/skin type materials.
* '''Subsurface Color''' - The general color of light given off upon entering an object due to subsurface scattering.
