We haven’t finished recreating all of the old sculpty themes in mesh for the new system. This is an ongoing project, and we apologize for the inconvenience. As soon as a sculpty theme you owned for the old system is available in mesh, you’ll be able to request a free updated copy. Join the customer group for updates about new releases.
In the meantime, if you owned any sculpty add-on themes prior to migration, you will receive a Legacy rezzer that will allow you to use those with your new licenses. The Legacy table works just like the old tables did, with the themes accessible through the tabletop menu.
