Hi, hope to find you well.
We are currently experiencing an error in a multi-machine setup, where when we run a scene cooked for Aximmetry in Unreal Engine the loading of the project proceeds smoothly, in spite of the fact that the scene is particularly complex, but as soon as we insert the scene OUT pin into the LEDWallCam RENDERED pin node the remote renderers lose connection and show the error described in the title of this thread but in the log console there are no errors.
What could this error be due to? I hope you can help us because we have been trying to solve this problem for a whole day without succeeding.
Any help is very much appreciated, thank you.

Hi,
If the output pins of the Unreal module are not connected to any active output, then Unreal is not running:
As soon as you connect it to an active output, it will start running and loading. During this loading phase, Aximmetry and your computer might become overloaded, struggling to execute everything within reasonable intervals. This can lead to the remote machines failing to signal their active status to the controller machine.
Using the repair connection button should resolve this disconnection. However, this action will restart the compounds on the other machines. Therefore, it is advisable to initiate your compound in Aximmetry with the Unreal module connected to either an active output or to a Force Execution module.
For more details on Force Execution and what constitutes an active output, you can read the Module Execution section of our documentation.
If you wish to avoid having your Unreal Scene running continuously during your production and prevent hiccups when Unreal is loading, you could consider creating an empty persistent level in Unreal and loading your scene's level in the background (hidden). By loading your level in the background at the start of your production and only making it active when necessary, you can minimize loading-related disruptions. It is described how to load levels in this manner in the second image here: https://my.aximmetry.com/post/3279-unreal-level-loading-with-blueprint-does
Warmest regards,
