If, as happens to us all once in a while, you import a sculptmap that has been made in a different application into blender and find that it has a big old split down one side, try this:
- Add a plain, unmodified sculpty with the same stitching type as the one with the split.
- Add a multires or two so that it has about the same number of verts as the original with the split.
- Select it in Edit Mode and go to Mesh => Scripts => Update from Sculpty
If that makes no sense at all, Gaia Clary who wrote the tutorial explains it beautifully, with video, here: http://blog.machinimatrix.org/fix-the-gap/
