does anyone know what causes the duplication? The HP is comprised of several layers that have been merged for a normal map. And then the LP is also made of several layers that have been merged.
What duplication? Can you be more clear? Its not really obvious whats the error, based on your text and image.
The little patch has been duplicated. I haven't exactly connected the vertices of the LP together, so I think that's why it's causing the patch to be duplicated both on the top base mesh and the mesh of the patch itself.
Well, on the base mesh all the high res meshes are projected as sources, so the patch will also project. If the highres patch was a tall cylinder for example, it will project, but be cut depending on the cage distance (or ray projection distance).
So it isn't a technical issue. You can export a high res of everything but the patch, and one of the patch, and in xnormal make a bake for the basemesh and one for the patch.
Or you can setup projection groups in bakers that support them - this will link low poly base mesh to high res base mesh (but without patch) and low poly patch to high res patch. So there will be no projecting issues.

I am trying to make an in-game model, so I would like to have just one map instead of many, I've never used projection groups, but would that make multiple maps or just one?
