I assume you know how to make new skintone projects in bodyshop. If not, there are tons of tutorials over at MTS2, and I'm sure there are a few here at insim too. Making a new skintone project is the first step.
Do you know how to work with layers in GIMP? I think it's much the same as Photoshop, but I've never tried GIMP myself, so I can't say for sure.
Locate the baby face texture (marked "
buface") in the project folder. Open this and the TIFF file from the download in GIMP, From then, it's pretty much drag and drop. If you're really lucky, GIMP has the same shortcuts as PS, and drops the layer on the correct place at once if you hold in SHIFT. If not, then just position the layer where you want it.
Collapse the layers (CTRL + E, or "merge layers" in PS), and save.
If you're smart, you also fix up the file named "swap", so that you'll find your skintone a lot easier ingame.
Then click the update button in bodyshop.
Giving the file a description is also a good idea.
Then all that is left, is importing the file to the game.
It's not hard at all
