After launching the session on the cluster-side, you need to go to Preferences/UVR PredictSuite/Engine Cluster and  fill-in information on the remote machine including the address and port, the username, password and the absolute path to where the remote assets are stored.

Clicking on connect to server  enters predict-unity remote mode, all subsequent renderings within this session will be executed remotely. To end a session, click on disconnect from server  before closing the session on the cluster-side.

Predict-hpc uses remote services to synchronize assets between the client and the remote cluster. Clicking on Synchronize will upload every assets in the current Unity project to the cluster, only updating  outdated or modified assets for more efficiency. By default, in remote mode, the scene is automatically synchronized when pressing play but you can pre-synch most of the assets while woking on the project to gain time.

Clear Cache can be used to wipe the distant assets directory for a clean synchronization.

You can monitor assets synchronization from within PredictSuite/Engine/File synchronizer monitor.
