Multiple NDI Broadcast actor

Hi! How can i connect multiple camera actors to one NDI MediaSender? I want to switch between cameras and send one NDI stream (signal) to OBS.

Each NDI broadcast source needs its own instance of an NDI sender. You would basically create your cameras then an equal number of NDI senders ensuring that you update your blueprint to call them all start on Event_Begin_Play. So every output will be an independent stream with its own name allowing them to be switched in OBS,VMix etc.
