  1. Drag a group from the Hierarchy into the GroupMeshScript field or use the circle button and select a group from the list

Closing, opening and disbanding groups:

  1. In GroupMeshScript click on close group to pack the meshes into 1 mesh. Now the group can no longer be edited

  2. To edit a closed group you have to open it again. Click on open Group and the group is now ready to be edited again

  3. When you no longer need a group but want all the objects back to their original positions in the hierarchy, click on disband group
