Marmoset bakes WHITE roughness

Yoji

So I have this mesh with 8 texture sets and I didn't want to combine my textures with PS or SD after I painted it in SP, so I instead decided to use the original baker file (replace the highs with my lows) in Marmoset and bake my comp maps like base color, roughness and metal.
I told Marmoset to bake these 3 and it worked like a charm, EXCEPT roughness which turned out white.
I fixed my issue ofc by reloading the textures into albedo instead and rebaked with a different name but it was still bugging me that originally my roughness decided to be white. I ran a few tests with inverting roughness on the shader and loading different maps but they still come out white.
Any ideas why this happens?

Were you using Gloss or Roughness for the input on the high poly material?

Yoji

I was using Roughness.

There could be a bug with that, the Roughness module was added relatively recently. Can you try setting it to Gloss and clicking the invert check, and seeing if that gives you the correct result (when baking a Roughness map output)?

That works! I've struggled 2-3 hours trying to bake the roughness. Thank you!

You can bake rougness map as Albedo seperately
