!Help - Tattoos on shoulders

I hope someone can help me with this problem I've been trying to deal with for the past couple of months.

Placing tattoos on shoulders for the genesis 8 models (female and male). Specifically the deltoid. Due to the way the UV maps are designed for the torso and arms, its splits the deltoid in half at the torso UV map and the bottom part of the deltoid continues in the arms UV map. This makes it really difficult to put a tattoo thats meant to cover the entire deltoid and seem seamless. Especially the on the torso map, as the split section is also rotated. I've tried manually cutting the PNG file and aligning them to each part of the UV map where I think its going to be and using trial and error. but the process is tedious and results are not good at all. There HAS to be an easier and more efficient way. Does anyone have any ideas on how to achieve this? Thus far I've only tried doing it manually via Photoshop on the UV maps and I've tried manually positioning it using the L.I.E on the torso and arms to align it.

Heres an example of what I mean...

    I also wanna know a better LIE way of doing so since I ever tried but finally gave it up. Suggest you avoid putting a tattoo on that part of shoulder. Or you may use Geoshell tattoo or decal tattoo instead. That'll be much easier and faster.

    You may check 2 products: IDG Watercolor Tattoos 1 (Geoshell tattoo)、Iray Tattooz (decal tattoo). I learnt from these products.

    A) Iray decal.

    B) Bake the tattoo textures in Blender.

    Thanks for the suggestions! I have tried the decal route but it's not a solution for myself as I create a lot of poses and still images in a comic and that requires me manually moving the decal as well each time I pose. But I'll look into the Baked tattoo textures in Blender option by @margrave. 

    I'm hoping for a set it and forget it solution wink

    It's fairly involved, actually. What you need to do is take the G8 into Blender, create a second UV map (making sure to leave the original map), and use the "Project From View" unwrapping. Then you position the tattoo texture on the UV map where you want it. You go back to the original UV map and bake the texture(s) so that the projected tattoo is positioned correctly on the UV map that came with the figure. Finally, you bring it back into Daz as an LIE texture.

    It works, but it's complicated and I'm probably missing some stuff. Luckily there's quite a few tutorials on baking textures on Youtube.

    No, nothing in particular. Just watch as many as you need to get it.

    @potatopealor I suspect you would benefit greatly by utilizing the seam guides for the particular generation of character you are using. (Genesis 3/8 are the same)

    @dtrscbrutal

    I never thought about using the seam guide but wow...i wish i looked at it earlier since i'm basically doing trial and error for tattoo instillation right now. makes life a little easier. cheers for that!
