mesh split while sculpting work after UV unwrap....

[gimong910]

I was sculpting a shark. By the repeatative work of UV unwrapping in Zbrush and export displacement map and normal map,
I suddenly realize some parts of the mesh has been split…! (like the image below)

The mesh was totally connected (plane without any hole)

The cut seems similar with the seam line of UVmap.

Why this happened? Can I reconnect this cut anyway?
One of my solution is just exporting the obj to Maya and merge vetexes respectively…But too time wasting…

plz give me any advice… Thanks in advance!

It’s impossible to know what happened without knowing the exact steps that have been followed.

One way to fix this is to use Tool>Geometry>Close Holes. This will do exactly what it sounds like.

Another thing that might work is the nearby Fix Mesh button.

Alternatively, make sure that the points in the problem area are as close to overlapping as possible (not pulled apart). Then export the model, select the PolyMesh3D tool and increase the setting of the Tool>Import>Weld slider. Now when you import the model, the overlapping points will be welded.

Hopefully one of those will help fix this!
