# Proximal Shader

![Image: 004434.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/004434.jpg)\
Particles and object edges can be illuminated or deformed.

Proximal is a shader that is based on distance dependencies. The shader outputs a luminance value based on how far away the surface being shaded is from a specified object (you can choose whether the object origin, points, edges or polygon center should be used). Proximal works best in the **Luminance** channel.

Proximal also works with particles (with Cinema 4D particles and with Thinking Particles). A luminance effect will be generated each time a particle hits the surface (see the example above).
