Need help with merging reliefs

Hey all,

Trying to put a clipart onto another relief. however, I don't want it to pick up the background texture. Attached the image of what I am trying to do. So I tried using ArtCam layers, and different combining methods. I need to be able to use something like merge high, where the second relief(batman) fits nicely on the surface of the model, but does not pick up the texture underneath. Replace does not work, since it does not bend the clip art around the model.

Please help me out.

You need to delete (zero) the part on the texture layer that you don't need.
