The tga image in pearthane alpha is 230, setting in SkinStudio for start panel effect is blur, but from checking
WB's with alpha start panel, color seems to make a big difference. To have it look like pearlthane you would need
to use settings and very close to same color. If you have, if not download, Bloss and StealthOS, both have alpha
start panel. By looking at a few examples may help you get the look you want.
