     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.

     •   Installing Avid Maestro | Virtual Set on Windows

Solution Overview
     The illustrations below present an overview of the entire Maestro | Virtual Set solution.

     Using Mixing Between Engines

     The following hardware components are used in the above Maestro | Virtual Set solution:
     •   Render Machine - HDVG4 or Maestro | Engine 4K
     •   External Chroma Key Device - ULTIMATE
     •   Camera + Tracker
     •   Genlock Generator
     •   Control_Data Server
     •   Control PC
HDVG4 render machine provides two renderers, separated by domains. Unreal Engine is only
responsible for background rendering. Its output is going into mixing source for Render Engine,
which adds the Augmented Reality objects, insertions, Garbage Matte etc. The output of the HDVG4
machine is mixed with the Background, the Foreground and Background Matte (also known as an
Alpha channel).

The output of the Render Machine (fill + key) is connected to an external ChromaKey which is
responsible for final mixing between Virtual Studio Background, Augmented Reality Foreground
and Camera Feed.

Independent engines - BG only from Unreal

The following hardware components are used in the above Maestro | Virtual Set solution:
•   Render Machine - HDVG4 or Maestro | Engine 4K
•   External Chroma Key Device - ULTIMATE
•   Camera + Tracker
•   Genlock Generator
•   Control_Data Server
•   Control PC

HDVG4 render machine provides two renderers separated by domains. The UE is only responsible
for background rendering. Its output is going directly to the Ultimate Chroma Key device as the
Background input (BG IN). The RE is adding Augmented Reality objects (LAYER IN), alpha
channels for them (LAYER MATTE IN) and dedicated Garbage Matte (G MATTE IN).

The output of the Render Machine is connected to the external ChromaKey which is responsible for
final mixing between the Virtual Studio Background, Augmented Reality Foreground and Camera
Feed.

                                               13

                                                       15
d. FreeDOS should be loaded. Go to LOCALE > cd LOCALE and execute flash.bat.

c   Do not remove the USB drive or unplug the power supply during the BIOS update!

        e.   Wait until the BIOS update is complete, disconnect the USB flash drive and restart the
             machine.
     2. Install CentOS 7.4 and configure it.
     3. Upgrade screen formats database file for libdvg-813.1-7.el7.centos.x86_64.
        a.   Copy scrfmts_unreal_59_50hz.tgz to /data/public/.
        b. Unpack the contents.
             cd /usr/dvg
             mv scrfmts scrfmts_old
             tar xfzv /data/public/scrfmts_unreal_59_50hz.tgz
        c.   Verify the md5 sum.
             md5sum scrfmts
             You should receive the following response:
             abd64114dd1a330f0c070761169edded             scrfmts
        d. Reboot the machine.
     4. If you don't have RAID yet, then create RAID10 for 4x 3.5'' HDDs for Clips.
        Use scripts create_raid_10_ver1_6.sh and remove_raid_ver1_4.sh for an automated creation
        of RAID-10.

n   After executing the creation script, the Clips share should be available through the samba share.

           Engine and click Install.

                                                            20
3. Generate license named MaestroVirtualSetEngine 2018.6 (usr/local/orad/license.dat).

   n     Without a valid license you will not be able to load any project to SceneLoader.

Configuration of Lens Distortion

         Then, configure the lens distortion as described below.

         Configuration of Lens Distortion

         There are two type of distortions implemented: Mode1(default) and Mode2. To change the used type
         of distortion, edit the Game.ini file.

         [/Script/AvidCamera.TrackedPawn]

         DistortionsType=Mode1

   n     Possible values: None, Mode1, Mode2.

                                                         21
When Mode 2 is selected, additional parameters need to be set:
•     EnlargeView: true or false
•     TexelsInCorner: true or false
•     TextureSize: integer value (power of two), default 32

Controlling of Lens Distortion

If you need to control lens distortions to match Render Engine, then you need to create an export in
the scene.

To control lens distortion:
    1. Go to the Blueprint Editor.
    2. Create an export.
    3. Add a TrackedPawn node.
    4. Grab “Set Polite Scale of Field of View” node from the Tracked Pawn.

    5. Create export.

    6. If in the RE.xml file you have the following info:

                                                   22
Then, using a controller send to this export value “1.12”.

Tracking with the Xync System
       This topic describes how to configure the Xync tracking for the Maestro | Virtual Set solution.

       To configure Xync tracking:
        1. Configure Xync by means of the Xync WebSettings with single tracking channel per target. For
           more information, see the Xync 2.0 User Guide.
        2. Inject channels in /data/WebSettings/modules/modXync/data/
           TrackingSet_.cfg/ on the Xync HDVG.

           Where:
           CHANNEL 1 is for Render Engine and should be configured the same in RE.xml file.
           CHANNEL 2 is for Unreal Engime and requires  (UE
           uses unicast connection for Tracking Data).
        3. Allow for proper multicast routing on Xync HDVG:
           route add -net 224.0.0.0 netmask 240.0.0.0 eth0

                                                       23

4 Starting the Avid Maestro | Virtual Set System

      In this section:
      •      Render Engine
      •      Unreal Engine
      •      Controlling Maestro | Virtual Set

Render Engine
      Render Engine should be run on domain=0.

      To run Render Engine:
      t      Type the following command:
             cd /data/RE/bin;
             ./start.sh domain=0

  n   Render Engine will now generate an RE0.log instead of RE.log.

Unreal Engine
      Unreal Engine should be run on domain=1.

      To run Unreal Engine:
          1. Prepare the desktop. It will set the boardset format to the one which is saved in the
             HdvgCpProfile.xml generated from the Control Panel.
             cd /data/SceneLoader
             ./mstart.sh
There is visible mouse cursor after starting the SceneLoader. To remove it from the view, start
  the system with the -nocursor option:
  -   remove /usr/bin/X
  -   create text file /usr/bin/X:
  #!/bin/sh
  Xorg -nocursor $*
  -   add an executable flag to the file:
  chmod a+x /usr/bin/X
2. Update the configuration of SceneLoader:
  updateConfig.sh

                                              28
This commands updates the configuration file(s) stored in the default location (/data/
          SceneLoader/SceneLoader/) and uses the HdvgCpProfile.xml file from the default location (/
          Control_data/config/HdvgCpProfile.xml).
        3. Run SceneLoader with the following command:
          cd /data/SceneLoader/
          ./mstart.sh

Controlling Maestro | Virtual Set
Controlling with PuTTy
       Open PuTTy, and Connect to UE/SceneLoader (HDVG machine):

                                                    29
Field                                              Value

         Host Name (or IP address)                          

         Port                                               8890

         Connection Type                                    Raw

ReTalk3 Commands: load/activate scene, set export, play animation, deactivate scene, unload scene

         Load Scene

         [1] Scene.Load(PathName="\Control_Data\Projects\Sample2018_6\Sample2018_6");

         Activate Scene

         [2] Viewport.ActivateScene(Canvas="Canvas1", Channel=1,
         Scene="\Control_Data\Projects\Sample2018_6\Sample2018_6");

         Set export

         [3] Export.Set(Scene="\Control_Data\Projects\Sample2018_6\Sample2018_6",
         Export="Cube_X", Value="0");

         In this example, the Set export command changes the visibility (true/false) of an object.

         Set export

         [4] Export.Set(Scene="\Control_Data\Projects\Sample2018_6\Sample2018_6",
         Export="Sphere_Scale", Value="5");

         In this example, the Set export command it moves the top-right object to an X,Y,Z position (vector).

         Run animation

         [5] Animation.Play(Scene="\Control_Data\Projects\Sample2018_6\Sample2018_6",
         Animation="MatineeActor_0");

                                                          30
Run animation

       [6] Animation.Play(Scene="\Control_Data\Projects\Sample2018_6\Sample2018_6",
       Animation="Anim_seq")

       Deactivate Scene

       [7] Viewport.DeactivateScene(Canvas="Canvas1", Channel=1);

       Deactivate Scene

       [8] Scene.Unload(PathName="\Control_Data\Projects\Sample2018_6\Sample2018_6");

Controlling with Maestro | Live
       You can control Maestro | Virtual Set scenes using the Avid Maestro | Live Controller.

       To work with Maestro | Live:
        1. Start the Maestro | Live Server.

        2. Go to: Devices > Render Unit Manager.

        3. Add an Unreal Engine device:
           a.   Enter a name and an UID for the device
           b. Enter the IP address of your HDVG machine.
           c.   Select Render Unit / Unreal as the device type.

Installation Problems
     Problems Accessing the Network Location path_to_unreal

      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.

                                                       36
Configuration Problems
     Used format is different than what is defined in the HDVGControlPanel

     When the host name is set to default instead of the actual HDVG host name, problems can occur.
