Hey guys I am trying save my gloss map into specular map inside photoshop, So I can use my gloss map inside Marmoset toolbag. I know how to just save a normal alpha like if I was going to make a transparency map. But I have no clue on how to save an image into the alpha, any help would be very much appreciated!
in photoshop you can make an alphachannel (window->channels) press the create new channel button, activate the channel and paste your map in there then save it out as a 32bit tga
