I brought this model from the other program. I wanted to practice sculpting with this.
clicked the Remash button with voxel size 0.01 and happened like this.
I thought that the problem was the up-and-down of face but it is not.
I cleared the normals data and remashed it but it was same
and all edges are linked each others except the back of the head
I can’t find what’s the problem.
