Operating Gang Mode
Engine Display Toolbar
The following example contains three different Engines, as shown in the image above. All three Engines have the following setup in common:
  • Engines are launched with the same Unreal Project (*.uproject)
  • Engines are running in Configuration Mode
  • Engines have no RGraph
Examaple Node Tree
Create the node tree as shown on the image above by following connections:
  • EngineControl node’s Display input pin to Mixer_0 node’s Program output pin
  • Mixer_0 node’s Channel1 input pin to Camera_0 node’s Output pin
  • Camera_0 node’s Track input pin to UserTrack_0 node’s Track pin
The node tree is ready.
Now:
  • Select the node tree except for the EngineControl by clicking and holding your left mouse button and dragging over the UserTrack_0, Camera_0, and Mixer_0 nodes
  • Copy the node tree you selected by pressing CTRL + C on your keyboard
  • Go to the Engine Toolbar, choose Engine02
  • Paste the node tree you copied earlier into Engine02’s Nodegraph by clicking CTRL + V on your keyboard
  • Connect the Mixer_0 node’s Program output pin to Display input of the EngineControl node inside the Engine02
  • Go to the Engine Toolbar, select Engine03
  • Paste the node tree you copied earlier into Engine03’s Nodegraph by clicking CTRL + V on your keyboard
  • Connect the Mixer_0 node’s Program output pin to Display input of the EngineControl node inside the Engine03
Please remember that Gang Mode is a Nodegraph operation requiring identical Node types with the same name.
All three Engines have the same RGraph construction, as shown in the image above.
Now:
Multiple Engines for Gang Mode
  • Select the UserTrack_0 node located inside the Engine01
  • Go to Input properties of the UserTrack_0
  • Change the User Transform X value from -500 to -400
Since all three Engines are included in the Gang Mode, the change you made in the User Transform X value is reflected in the Nodegraph of the Engine01 and the Engine03, as shown in the image above.
