[Bug] Paint Room: Color To Gloss, broken

Using: 4.9.17 on Gloss/Metalness Workflow

Maybe I'm just not understanding how this works, but I'm pretty sure I've used it in the past. I have a paint layer with greyscale values. I right click this layer and use the "Color to Glossiness" option, but my gloss channel remains pure black.

I can just import this greyscale texture as a glossiness map and do it that way, but that's sort of a 1-way street. I much prefer to tweak spec values in photoshop, but 3dc's spec layers are blank, which is why I prefer to start with black/white texturing.

Same here, still.

I forgot to paint along my gloss and vaguely remembered to have seen this in the past somewhere. I discovered it being in the menu when right clicking a layer. Clicked on it, but nothing happens

It seems currently it does nothing. Would be nice if it was functioning (jus nitpicking :P ) ... but as it is there... it is tempting to wanna use it :D

But I understand there are probably more important things in progess.

After testing...
For this feature to work, I have confirmed that the Glossiness channel must be set to 'On' at the time of painting to work.

If it was painted with 'Off' state, there is a problem that it will not work even if you turn it 'On' later.

I think it's definitely a bug.

+ Textures - Adjust - invert glossiness also same issue
+ Layers - Copy channels (RGB to glossiness) also same issue
+ Layer Blending - Additional glossiness also same issue
+ Layer Blending - Additional Metalness also same issue

OK, here's a little trick.

1. Select the color channel area with Freeze - Freeze Transparent Pixels.
2. Turn off the Color and Depth channels.
3. After turning on only the Glossiness channel, set the Roughness to 100% and then use the Fill tool set to Fill w/ color.
4. Glossiness channel will be added to the painting area.
5. Now try using Color to glossiness again.
