OK I did a bit of experimenting, and here's what I came up with. Source art 150x150 / 32-bit / 5.71 kb Steps: 1. Save the artwork as PNG's with transparency 2.

just some troubleshooting questions, was the targa exported as 24 or 32 bit? (32 is needed for alpha to work) is alpha is luminance in the texture file node checked or unchecked? (sometimes that helps)
use targas. if you have an alpha channel in any of your maps that you are using for transparency....save as 32 bit. actually, i just save everything as 32 bit.
