hi, version 4.5 export PBR to unity 5, if use Gloss/specular work flow there save texture to png format havn't problem, glossness map is in alpha channel. 

But if change work flow to Gloss/metalness, I can't find glossness map in alpha channel with same png format, metalness has a single texture, glossness has another single texture, how to solve this problem? Thanks.

Q. What is the workflow to export PBR maps that are compatible with Unity 5?


In the Paint Room go to Textures>Texture Export/Import Workflow and choose your preference.

Paint your model.


For Roughness/Metalness workflow:

Go to Textures>Export>Color/albedo Map (name it with _Albedo)

Go to Textures>Export>Normal Map (TS, Low-Poly Mesh) (name it with _Normal Map)


Go to Textures>Texture Export/Import Workflow and choose Gloss/Color Specular

Go to Textures>Export>Specular Color (name it with _Metallic)

(Optional) Go to Textures>Export>Emissive Intensity (name it with _Emission)


In Unity, using the Standard Shader:

Drag Color/albedo Map on Albedo channel

Drag Normal Map on Normal Map channel

Drag Specular Color Map on Metallic channel

Drag Emissive Intensity Map on Emission channel and choose emission color.
