Material made from two textures

Hey hivemind,
I got a simple question, but I simply can’t find an answer to it.

I want to create a surface, masked, unlit material out of two (or possibly more) textures for a sprite.
I have a texture showing the head of the character and a picture of the body, both at their respective place in their image. If you were to blend both images together outside of UE4 they will fit.
Inside the material editor I have set up the Paper2D Sprite texture and the additional texture for slot #0 and blended, added, lerped and multiplied both textures in multiple tries. All have the same result. The additional texture gets cramped inside the Paper2D Sprite texture.

I’m having problems of showing screenshots of the results and the material right now, sadly.

What would be the best way of connecting the two textures?
Thank you very much in advance!
