Packs guide your series’ look, story, world, tone or sound. Choose a direction that fits your idea, then review the scene before rendering.
Choose and apply a pack
Open the intended series, browse its packs and select a pack to read its description and Gem quote. Choose Add to series when you are ready.
Look, World, Sound and Heat: one active choice in each category. Adding another replaces the active choice.
Story: you can combine directions that work together.
Beat: queues an instruction for the next scene proposal.
What will change?
A pack guides new or revised work. It does not automatically redraw character or location references, replace finished clips, or generate a music track. For an existing scene, review Script, Cast and Location and make the intended revision before deciding whether to render again.
Music is opt-in after the October 9 update. A Sound pack chooses music for the episode when it is finished; merely selecting the pack does not instantly create a track. You can also ask Coach to Add music, or choose a paid on-demand score from the dock. Without a music choice, a newly finished episode has no background music. Older finished episodes keep their existing audio. Standard Finish episode is 0 Gems; Compose the score / Recompose the score on demand remains a separate paid action. A new score does not repair dialogue inside a clip.
How pack charges work
A paid pack is normally charged once for the series you add it to. Removing and re-adding a pack already paid for on that series normally does not charge again. Another series can require a new payment. Older account-wide purchases and refunded purchases can behave differently, so check the current quote.
Pack applications and scene renders are separate. A 0-Gem pack does not make video generation free. Heat packs do not override Mochi’s content guidelines.
If something goes wrong
If adding a pack stays loading or a charge looks wrong, pause repeated purchases. In your current support conversation, tell us the series, pack and what happened. If you have not started a conversation, use Profile → Support. A screenshot helps when available.

Pack confirmation will not open on iPhone
The 1.1.6 update includes a fix for a pack purchase confirmation sheet that could become unresponsive. Let the latest background update apply when no payment or unsaved edit is in progress. If the sheet still freezes, tell us the series, pack and what happens. Do not repeatedly tap purchase or buy again to test it; a freeze alone does not prove whether a charge occurred.
