Smoothing groups divide individually

[ChristopheDegraeve]

Hello,

I have made a low poly rock and I want to start sculpting some detail on it.
I imported my .obj with the crease smooth groups zplugin but when I divide my mesh, it divides the smoothing groups individually instead of dividing it as 1 mesh.

Does anyone know what causes this problem? Could it be my mesh or a setting in zbrush?

Here are some pictures to clarify the problem.

Your groups have duplicate points which mean that they are essentially separate meshes. You can fix this easily - before subdividing - by pressing Tool>Geometry>Modify Topology>Weld Points. You can adjust the WeldDist slider if necessary.

You would have been better off making the rock in ZBrush from the start. I mean it’s just a rock and they are so so easy to make in ZBrush.
