Advice for adding a texture onto an existing one?

Vint

Using Blender, I'm wanting to add a sort of tattoo onto an already existing texture for Ilinir, but the location is where the mesh seams so simply pasting it on causes it to distort heavily. Any advice on how I could get it to retain it's image? I'm new to Blender but can't seem to find a way to do something like add the image onto the 3d model so it automatically adjusts onto the flat texture image, trying to google it mostly just pulls up old basic tutorials on unwrapping the mesh and basic texture application.

I think thats what you are trying to do.

i tried it myself works fine on 2.80.72

did some testing on the cat on a seam

image used was 900x900 and the skin texture 2048x2048

but keep in mind everything you do is mirrored
