@mentions and cast

Type @ in a composer and a panel lists what you can mention: characters, elements, your Storage uploads and your last thirty image renders. Pick one and it becomes a blue token in the prompt; its sheet or picture is sent as a reference and its description joins the text. The Cast picker (up to four characters) and the Elements picker (up to eight) in Settings do the same thing with checkboxes.

Picture slots

Every image model reads a set number of pictures; the pickers show "N / max" and refuse beyond it rather than quietly dropping one. A character mentioned and also cast takes one slot, not two. Switching to a model with fewer slots trims the stack; switching back restores it.

In video and Cinema

On the Video page the cast lives in the composer (not in Settings). In Cinema every scene carries its own cast, with no inheritance between scenes; speakers in the dialogue join it automatically. On engines that read no reference pictures, the page says so: the cast is redrawn from the words alone.
