there it was
ok, the only steps you don't need from it, is the #6 and #12-14, because these outfits don't have an alpha channel. you need a picture editing programme that supports transparent backgrounds, though.
you must also download an outfit that uses the mesh you want to recolor, and open that in SimPE
instead of the
“(~TA12~)-Diaper_Override.package” mentioned in the tutorial.
And save the texture as png 24 bit, because PNG preserves th texture better than jpg does (if you use photoshop, you can use the shortcut CTRL+SHIFT+ALT+S. Then a window will pop up that lets you save in this format).
in the #9 and 10, use the
DXT3 format - because this supports transparent textures.
Just ask me if there's something you don't understand.
