Author Topic: Export settings Unity Presets are missing the Smoothness (Glossiness)  (Read 1413 times)

When using PBR Metallic / Roughness workflow, and trying to export the maps, Unity Presets doesn't include Glossiness (Smoothness). It should be available in export window.

There is a way to export glosiness. Under Default Channels I can manually select Glosiness from "Custom Channels" and export it using Default (project workflow) preset.

Although this way it exports the Glosiness correctly, this results in incorrect Normal format for Unity. Unity uses OpenGL type of Normal maps. But exported normal map is different type end normals become incorrect.

This is frustrating, any help or workaround is welcome. Thanks.


When choosing the preset export Unity Standard the Smothness/glossiness map is stored in the Metalness alpha channel.
When creating a material in Unity in the Metalness slot you should have the smoothness option (see image attached).

Thank you

You could have informed the user about this in the UI. I didn't notice that.

Then why isn't AO also included in the mask map? AO is a separate texture. It should be;
Red: Metallic
Green: AO
Alpha: Smoothness

And you should call it something like (M_AO_SM) or mask map, instead of metallic.

These all are the same for each rendering pipeline.
