To start a render job in Chaos Cloud submit a scene through the client app or with a click directly from V-Ray.
If there are free resources in the cloud, Chaos Cloud will start rendering your job. If there are no free resources, your job will join a queue and will start rendering automatically when resources become available.
By default our notification service sends you an email if your job status changes from one of the active states to one of the final states ("Completed" or "Failed").
For more details take a look at Chaos Cloud Rendering documentation.
