I am modifying a 3D scanned model , I want to join the upper and lower parts of the shoe.
I didn't know how to do it in sculpt mode, so I did a merged the vertex in edit mode, but it didn't work. (Please refer to the image)
Also, I found an article asking the same question. https://blenderartists.org/t/how-to-fill-the-holes-and-avoid-overlaps-in-sculpt-mode/641648
Is this impossible even as of 2021 without using add-ons?
I'm new to 3D scanning and sculpting, and I'm sorry if it's a rudimentary question.
