I’m not great at this at all but Milcesimsox ask for a tutorial so I thought I’d give it a shot.

So, Step One. Obviously, open your image in photoshop. I used cs6.

I edited it a bit with the liqiudfy tool and clone tool, just to fix some things. You can skip this.

Step Two. With the quick selection tool, select your sim. This step work a lot easier if you take the picture of your sim in game with a plain background that doesn’t match anything your sim has on or their hair color.

Step Three. Right click with the quick selection tool still selected and choose Refine Edge.

Step Four. Mess with the settings until you don’t see anymore white. Sliding the Shift Edge slider down works but I always set the Radius to 0.5. Change the Output To to New Layer, then hit OK.

Step Five. Find the background. You want. This step is simple enough, get one google and find your image. I chose the top left one.

Step Six. Click the background and place or paste your image. It should be behind the new layer of your sim. Flatten layers and edit to your liking and you’re done.
