Your background disappears. You're cut from your room and placed on a shared set where the whole ensemble performs together. This is the difference between a video call and a production.
This is you, live, cut from your room and standing on the set, running entirely in your browser, no Zoom, no Google, no third party. The other positions are where your fellow actors appear once the live video engine is connected, then the whole ensemble shares this stage, each cut from their own room, all on the same set. That's the production. This is the proof.
