# Lumas Shader

![Image: 004426.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/004426.jpg)

Lumas is an illumination shader that includes three specular highlights and the ability to simulate the anisotropic scratches that tend to produce elongated highlights in particular (see vase above).

Lumas is useful in combination with Fusion and other channel shaders or images.

The [Reflectance](https://help.maxon.net/c4d/en-us/Content/html/MMATERIAL-ID_MATERIALGROUP_REFLECTION.html.md), which is much more powerful, should also be used occasionally.
