Texture Export Trouble

I am trying to export a custom texture file, but the specular is not exporting. I am receiving the following error codes:

[MapExporter] The input map 'Specular' needed by the map 'fatigues_s' of the texture set 'DefaultMaterial' isn't available because: 'Specular' channel is missing in your texture set.

[MapExporter] The input map 'Glossiness' needed by the map 'fatigues_s' of the texture set 'DefaultMaterial' isn't available because: 'Glossiness' channel is missing in your texture set.

[MapExporter] The map 'fatigues_s' can't be generated for the texture set 'DefaultMaterial'.

I have enabled the specular level in the channels. I have also painted a layer using metal settings and set a metal material on some of the items in the texture. I am not sure what I am missing.

Hi @bog_witch,

Make sure your shader supports "Specular" and that it's enabled in all Texture Sets. Currently, the error indicates that it's not in enabled in your Texture Sets.

This is my current texture setup. I am still getting the following errors.

[Project management] Save successfull
[MapExporter] The input map 'Specular' needed by the map 'fatigues_s' of the texture set 'DefaultMaterial' isn't available because: 'Specular' channel is missing in your texture set.
[MapExporter] The input map 'Glossiness' needed by the map 'fatigues_s' of the texture set 'DefaultMaterial' isn't available because: 'Glossiness' channel is missing in your texture set.
[MapExporter] The map 'fatigues_s' can't be generated for the texture set 'DefaultMaterial'.
[StacksExporter] Map export ended

What do you think I should check next? Could it be something in the export settings?

As mentionned, your projects doesn't contain a Specular channel or a Glossiness channel. Therefore, if you want to keep your shader as it is and not use the dedicated Spec-Gloss one, you'll need to build a custom Export Template with converted maps.

Converted Glossiness = inverted Roughness
Converted Specular = Merging Base Color + Metallic

Otherwise, you can also use the dedicated Export Template PBR Specular Glossiness (converted from Metallic Roughness).
