@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 Add character and Add context elements buttons above the composer write the @ for you and open the list on that kind; Settings has no separate cast or elements picker.

Picture slots

Every image model reads a set number of pictures; the picture stack shows "N / max" and refuses beyond it rather than quietly dropping one. Switching to a model with fewer slots trims the stack; switching back restores it.

In video and Cinema

On Video, as on Image, the cast joins by @Name, with the same two buttons above the composer. 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.
