Hello, I have two separated meshes:
Mesh A: a head without her mouth. Since there is no mouth, this leaves a huge hole on her head.
Mesh B: her mouth
From the back view, you can see the mouth mesh is a non-manifold as well. So it is not a closed mesh, but a single layer of mesh, and the edge of the mesh do not connect anything.
I want to combine the two meshes into one single mesh.
Some Methods I was trying:
I have tried to use "Ctrl + j" to join the meshes, and in the Edit mode, select the corresponding edges and press "f" to build new faces to connect the two meshes. But the result is a failure, since it automatically builds some unwanted new faces and meshes, as the following screenshots show:
By the way, using the Union in the Boolean modifier is also hard to work. The result can leave some spikes or many disconnected tiny meshes inside of her head. Those unwanted meshes can cause trouble for future sculpting.
Thank you for reading!
This is going to be tough to achieve with two sculpted objects, its not impossible, but will require an extensive amount of work.
Ideally you want the same number of verts on the the two edge loops on the face and on the mouth.
I would suggest the best option would be, join into one mesh with CTRL+J, and retopologise over the base mesh.
Or
Retopology first on both meshes, then CTRL+J to join them to one mesh, and then merge each vert around the edge loops.
Thank you for your reply!

Okay, it seems that the difficulty to solve this problem may be beyond my initial expectation. Ouch!
retopologise over the base mesh.
Actually, I only want to repair the base mesh, which is going to be used for 3D printing. I believe that although retopologized mesh is good for animation, but will lose geometrical details when 3D printing it out.
