Roughness map has no effect

taki39

I want to create a roughness map effect around my lips and eyes.

I want to brighten my lips and around my eyes.

For that reason,

I painted my mouth and eyes in gray.

I read it with the marmoset toolbag.

It had no effect.

What is the cause?

I'm not familiar with TB but, coldn't it be the 'channel' slot which is marking the 'R' channel instead of 'RGB'?
Plus: I think your 'roughness' map is actually 'glossiness'.

I used to think so too, but the "r" channel of a grayscale map is still the same information.
What's the rest of your shader look like? Metalness with  a black or zero value may help?

Are you being too subtle? Unless those areas are notably lighter or darker I don't think you'll see much... From the limited screencap, It's kinda hard to see enough to tell if this is the expected result.

I don't think this is the issue, either, but have you checked the settings/cog icon and toggled srgb to see if that makes a difference?
