Live inputs on objects
Select a rectangle or another paintable object, open Resources → Media, choose an Input, and press Use input here. The status shows the input and destination object. Use Other input… to enter a different name, matching the Nodos pin's letter case. The object owns this source directly; there is no separate cue or video-target assignment. The same controls are available from the object's Fill → Live input setting.
To preview a camera on that object, press Start webcam or Use webcam here in the same card. This applies the selected input to the object before starting or redirecting the camera. The webcam is a local preview of that input; the exported page receives the named texture input from Nodos. Fit, crop and focal-position controls stay with the object's fill.
