You can export your scene to work offline from a location where the Harmony server is not located. An example would be from the studio to your home. When you return to the studio, you can then import your scene to reintegrate it back into the Harmony environment.
If your scene has shared images, textures (used colour-overrides) and palettes stored at the environment or job level on the Harmony server, these links will be broken when you export your file. You can create presets to point to where these linked files are located. For example, you can store your images, textures and palettes somewhere on your home computer and create a preset to point to where these files are located. Then when you get back to the studio, you can select another preset that points to where the files are located on the Harmony server.
