Copy LIE edited image from one Layer to another

---

 

Hi, I have socks here, which i wanna give a dirty touch, but they have sadly 2 Layers Base color 1 and Base Color 2, for the pattern.

How can I easy copy the stuff Base Color 2 to Base Color 1?

I have to do that for 3 areas front/mid/back and that for 3 Layers, Base color, pattern and something more...

Any idea how to do it?.... on big sizes is the editor sooo slow :(

And IF the copy does even work... (from image 1 to image 2). it would not:

because it doesnt work there.

Iray view:

 

 

Atm it is under the pink colors and under the hearts.

 

Update; I made now a new own layer based on the texture and just load it... thanks to Gimp.
