About Node View Setup
Now that your environment variables have been properly set up, the final step is to prepare your network to call the Autodesk Maya rendering utility. Once this is done, you can render the 3D objects in your Harmony project and preview them in the Camera view in the Render View mode. This will allow you to composite your 3D scene and effects.
Use the Render Maya Batch node to connect Harmony and Maya.
This node uses the script
This script starts a Maya Batch session, renders the 3D elements on that frame, and then closes the session. It will open and close the session for every frame to be rendered.
