Ok, just had the look I should have had before; this is how the eyelash channel is on my figure. It's a Multi Channel Mixer. Source 1 is Multi Channel and the color can be set (if you want the lashes to be a particular color), shininess, highlight, can be set as you'd like. Source 2 is Multi Channel and everything is set to None except for transparency which is set to 100% The Blender Channel contains the trans map image. Now, in the file I looked at, the invert (invert image) button was selected in the image map section. I've also seen it not selected and work. So if the above doesn't work, one could try inverting (or uninverting) that toggle.
