PBS_Metallic component as seen in the Scene Inspector

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!

Behavior

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

Resonite uses the Unity Standard Shader Maps for this Material, for more information please see this guide for more information.

Other Maps

TODO

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

R: Metalness

G: Occlusion/Height

A: Smoothness
