# Transparent PNG cutouts

> Cast/Object isolate, World clean plates, and how credits work for generated visual assets.

Transparent PNG cutouts answer: **how do I turn a reference frame into a usable planning asset?**

Cast & World can isolate a person, object, or environment reference from the teardown. Use these assets for moodboards, style frames, layout tests, and production planning.

## The two asset actions

| Action                             |      Cost | Result                                                          |
| ---------------------------------- | --------: | --------------------------------------------------------------- |
| Cast/Object isolate                |  1 credit | Transparent PNG cutout of a character or object                 |
| World clean plate / person removal | 2 credits | Environment reference with foreground person or subject removed |

Charges apply only when the asset is successfully stored. Reopening the same stored output is free.

## When to use each one

Use **Cast/Object isolate** when you need a person, product, prop, or graphic separated from the frame. This is useful for moodboards, pitch decks, compositing tests, and communicating the shape of a shot.

Use **World clean plate** when the environment is the useful part: a room, street, desk setup, product backdrop, or location style that you want to study without the foreground subject.

## Good usage

* Use cutouts as planning references, not as licensed source assets.
* Keep the original teardown linked in your notes so the context is not lost.
* Use collections and moodboards to group cutouts by campaign, client, or visual direction.
* Download stored outputs when you need them in a deck or editor.
