Transition UVs seamlessly between Objects

[Tobe-san]

Body and breast are two seperate meshes which is intended. I achieved this result with the data transfer modifier. I’m happy with the borders, however the UVs of the inner parts of the breast has alot of glitches and overlaps. I tried unwrapping the glitchy parts seperately but the result wasnt satisfying. How do I apply the material of the body flawlessly to the whole breast mesh?

this is what the unwrap looks like after the Data transfering the Uvs

these are the data transfer settings. Any ideas how to improve the result?

Does the target mesh has seams at all?
If not, you can either try to transfer them as well (in Edge Data, I think) or set them manually.
