Workflow Presets & Data Mapping

• Where to find Material Regions:  (These Nodes are available in the Nodegraph only)

• Workflow Presets & Data Mapping
• Roughness / Reflectance (R-R)
• Metal / Roughness (MetalRough)
• Specular / Glossiness (SpecGloss)

Different Artists and Studios have different kinds of Channel Requirements.

Material Regions come with three default workflow flavours to support a good mixture of Game & Film workflows.

By utilizing the PBR Conversion Nodes you can also convert between workflows, giving you the freedom

to work in your preferred system and only worry about outputting the pipeline standard at the end.

Regions all have a common data chain (INPUT / OUTPUT) that is used to transfer data between regions.

For information, the mapping of Material Attributes to the different Inputs & Outputs is included below with each workflow.

A variety of Region Presets exist to work with different common workflows such as:

Supported Color+Alpha Channel Types (RGBA):

• Diffuse, Specular Color

Supported Color Channel Types (RGB):

• Normal Map

Supported Greyscale Channel Types (FLOAT):

• Displacement/Bump, Specular Reflectance, Specular Roughness

Input/Output Data Mapping:

• A.rgba  = diffuse;
• B.r        = Roughness.r
• B.g       = Reflectance.r
• B.b       = Disp.r
• B.a       = 1.0
• C.rgb    = Normal Map
• C.a       = Accumulated Region Chain Mask
• D.rgba  = specColor

Supported Color Channel Types (RGBA):

• Base Color, Normal Map

Supported Greyscale Channel Types (FLOAT):

• Height, Roughness, Specular Level, Metalness

Input/Output Data Mapping:

• A.rgba    = Base Color
• B.r         = Roughness.r
• B.g        = Metalness.r
• B.b        = Height.r
• B.a        = 1.0
• C.rgba   = Normal Map
• D.r        = Specular Level.r
• D.g       = Accumulated Region Chain Mask
• D.b       = 0.0
• D.a       = 1.0

Supported Color+Alpha Channel Types (RGBA):

• Base Color
• Specular
• Normal Map

Supported Greyscale Channel Types (FLOAT):

• Height, Glossiness, IOR

Input/Output Data Mapping:

• A.rgba  = Base Color;
• B.r        = Glossiness.r
• B.g       = Height.r
• B.b       = Accumulated Region Chain Mask
• B.a       = IOR.r
• C.rgba  = Specular
• D.rgba = Normal
