Skin detail problems

Hi,

I am no expert with skin details but if you want to use them with an EA default skin I would assume you need to use a composition method of 2 or 3 instead of here 0.
The composition method is used to make the additional layer you want to add, blend with the one under it. That way the potential differences in colors and so on are better blended together.

Also the main issue here is that your full alpha is white. That means that when you apply your texture, it will apply ALL the skin together with it.
The alpha of your texture needs to be applied only for what you want to add. Here: the freckles.
Simply export another skin detail from the game, like lipstick or the base freckles and you will see already in the thumbnail that only the lipstick/freckles are visible. That's because the alpha layer from the dds file (for the texture, here named diffuse) is only applied under the lips/freckles.

PS : If you want to use your freckles with custom skin, the best is to keep the composition to 0 the way you did, that's fine ^^
