ZBrush: merging borders

[system]

Hi folks.
I Have 20kk scanned mesh (on the left) divided onto 16 parts (example on the right).

How can I merge them together (In ZBrush or in any other program)?
Tried projection brush (to project geometry on the other mesh) but the mesh is too complicated to project without issues.
Thanks.

I believe you could accomplish this by duplicating the model and then using ZRemesher on it. From there you can use Project All to copy the details from the original to the new one. Divide the model and project again. Keep going until you’re happy with the polygon count and detail level.
