It would be incredubly useful to be able to rename NDI outputs. We have noticed issues with NDI when the names from VDMX contain the restricted symbol. Not all NDI receivers support this and end up unable to make a connection.
The NDI output name can be changed by double clicking the Plugin Name in the Plugins tab.
I had this same issue with Unreal Engine not recognizing the ® symbol - luckily we can change the NDI output name VDMX transmits.
