When are we going to be able to assign participants to a Zoom Input in vMix via companion? Its a giant miss that makes the integrated Zoom functionality very difficult to manage without it.

Has anyone been able to do this via scripting without OSC control?

Yeah I just tested it. As long as you have their name exactly as it is in Zoom it works. That name can come as a variable, but you still need to preset something ahead of time to make it work, unless you just type the name in directly to Companion. It doesn't look like you can get names from Zoom directly, but you can assign them if you know their names.
