I’m new to Z brush ( I have z brush 3) and was trying to create a base with zspheres. I saved my file and when I went to go back to work on it. It would not allow me to reselect my zsphere chain. To edit or add to it. It was forcing me to create a new z spheres. Is there away that I can select that old zsphere chain and edit it? The edit mode seems to be unselectable.
