1 Introduction
In this section:
• What is Maestro | Virtual Set?
• Maestro | Virtual Set Workflow
What is Maestro | Virtual Set?
A full Avid Maestro | Virtual Set system is made up of 3 software modules:
• Maestro | Virtual Set Authoring - set of plugins and templates for the Unreal™ Editor tool.
• Control Application - control Maestro | Virtual Set Engine and broadcast the graphics created
with Maestro | Virtual Set Authoring, with applications such as Maestro | News or Maestro |
Live.
• Maestro | Virtual Set Engine - real-time application for rendering the graphics to a video output
using powerful Unreal Engine on dedicated Render Device.
The Maestro | Virtual Set Authoring modules together with Unreal Editor address all requirements
for integrating your OAG applications into an automated studio. First, 3D graphic scenes are created
in the Unreal Editor, where you can define animated sequences and using additional plugins
determine what can be changed in real time by “exporting” functions to the Control module.
Reporters can then insert or import current data into the templates using a Controller, which can be
run from a remote station.
Maestro | Virtual Set Authoring takes the advantage of Unreal Editor and addresses it's power into
Virtual Studio creation tool.
Maestro | Virtual Set Workflow
The following workflow contains the main tasks performed when creating a scene in Maestro |
Virtual Set.

1. Check Registry entries:
- Open the Registry Editor:
- Go to: HKEY_LOCAL_MACHINE\SOFTWARE\EpicGames\Unreal Engine\4.18
35- Make sure that the InstalledDirectoryy is pointing to a real, accessible location (even an
empty folder).
Problems with locating the version of installed Unreal Engine
The MaestroVirtualSetAuthoring 2018.6 application requires UnrealEngine v4.19. If the version is
already installed on the PC but not registered properly in the system (missing entries in Windows
Registry):
HKEY_LOCAL_MACHINE\SOFTWARE\EpicGames\Unreal Engine\4.19\InstalledDirectory
uninstall it from the Epic Games Launcher and install it once again.
Problems with installing MaestroVirtualEngine on Linux machines
c The procedure described here applies only to the MaestroVirtualSetEngine_2018.6.120.exe
version!
The installer listed above may have problems with installing/updating packages on desired render
machines.
• If you have installed this version on render machine A and you want to install it again on render
machine B, then the installer automatically wants to remove packages from render machine A.
• Other problems may occur when you want to install this version on other render machines and
one of the already set up render machines is unreachable in the network - the installer wants to
remove it, but if it encounters connection problems then it fails and stops the installation.
• If you are going to install a new version of the application, the installer will try to first uninstall
the previous version on all of the already installed render machines.
To avoid these problems you need to edit windows registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Avid\MaestroVirtualSetLinux\HDVG and/or edit or
remove the IP address.
