SOLVED -PNG with metallic and smoothness - How can I edit (in PS) the two separately within one PNG?

Solved:

In Photoshop, if you open your PNG and then go to:
Layer → Layer Mask → From Transparency
It’ll create an alpha channel on your PNG for you to play with.

Hey all - so I’m stumped. I’m relatively new to Unity and am having difficulty getting used to using a PNG (format is client mandated) for metallic/smoothness. My PNGs are coming out of Painter which has combined my metal/smooth upon export.

I understand that the value AND transparency work together to affect metal/smooth. What I want to know is how I could go about editing/tweaking the two separately. I would MUCH prefer to use TGAs, where I could more readily access the color channels and alpha for editing independantly.

Any help would be much appreciated.

Better answer for you : use the free photoshop plugin SuperPNG : http://www.fnordware.com/superpng/
This will allow you to save and loag PNG like you would do with TGA : with transparency as an alpha channel.
The big difference with the method you mention is that you will not loose the color data where the pixel are 100% transparent.

Thank you very much for that. I really should have asked this question long ago. Seriously, thank thank you.
