PBS Metallic
This article or section is a Stub. You can help the Neos Wiki by expanding it.
PBS Metallic is a physically-based material that uses a special Metallic-Roughness (MR) map to store data about the metallicity and roughness of an object. It is based on the Unity 5 Standard PBR Setup.
For information about the maps and their properties read on!

Behaviour
Metallic Maps
This Material type uses a Metallic Map for determining:
- Metallic Levels
- Smoothness
This information is packed into different channels within the Metallic Map using the following pattern:
- R(Red Channel): Metallic
- The Red Channel determines how metallic a material is.
- Metals are usually 1 in this channel and non-metals are 0
- When choosing Metallic values, do remember that items in the real world aren't perfect. Imperfections and randomness is good! Avoid choosing values that are 0(Non-Metallic) or 1(Maximum Metallic)
- Alpha: Smoothness
- High Alpha means High Smoothness
- Low Alpha is Low Smoothness
Neos uses the Unity Standard Shader Maps for this Material, for more information please see this guide for more information.

TODO
Unity declares Green : Occlusion and Height as interchangeable and usable for both slots

R: Metalness
G: Occlusion/Height
A: Smoothness
