A useful tip

A model change does not alter media already generated. Keep important identity and appearance details in the message as well as in references.

If something goes wrong

If a file fails, retry or replace that file in Manage. If models cannot load, use the panel’s retry action; keep your prompt and references while it recovers.

Read first, create when you’re ready
