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 the Configuration Mode

  • Engines have no RGraph

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 the 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 the 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:

  • Select the USERTRACK 0 node located inside the Engine01

  • Go to INPUT properties of the USERTRACK 0

  • Change the USERTRANSFORM X value from -500 to -400

Since all three Engines are included in the Gang Mode, the change you made in the USERTRANSFORM X value is reflected in the Nodegraph of the Engine01 and the Engine03, as shown on the image above.
