A quick tut on how to make a tattoo with sims 4 studio and photoshop. I am assuming you have a basic understanding of s4s.

Im going to be making a back tattoo but you can make a tattoo for any part of the body you want. First things you will need are -

An image you want to use for your tattoo

And the body texture template from heresims4studio.com/thread/243/sim-body-texture-templates

Open s4s and clone out a tattoo as a recolor and export the texture and open it in photoshop.

On both the image layer and the alpha layer get white and black paint respectively and paint over both the images to make a blank canvas to start with.

Open up the body template texture and put in on top of the background image.

Open your tattoo image in photo shop and delete the background (I just used the magic eraser) and copy and paste it onto the body template (ctrl c ctrl v) then ctr t to transform and hold shift for uniform scale, scale it down and place it where you want it to go and hit enter.

You can delete or hide the body template now. So wind up with this

Now for the alpha layer

Either drag layer 2 onto the new layer tab, or right click on it and duplicate layer so you have layer 2 copy as shown

Make sure you are on layer 2 copy and click the fx tab
