What is in an asset, and how to get a second result out of it.
Every asset ships with the output, the source, and the prompt that made it. The prompt is the part worth learning to edit.
The anatomy of an asset
- The preview
- What it looks like running. Hover a card to see it move; the item page plays it in full.
- The prompt
- The exact text that produced the output, not a cleaned-up retelling of it. Free assets show it to any account; the rest need a subscription.
- The source files
- Whatever the thing is actually made of — scene modules, components, configs, weights, maps. Downloadable one at a time from the item page.
- The spec
- Where it was used, what it costs to run, what it depends on. The honest version, including the parts that are awkward.
Editing a prompt without breaking it
Most of these prompts are long because the detail is doing the work. The temptation is to rewrite the whole thing; the better move is to change one clause and re-run. A prompt that produces a warm studio set will produce a cold one if you change the lighting line and leave the rest alone — change six things at once and you cannot tell which one moved the result.
The clauses worth reaching for first are usually the light, the palette, and the camera. Structure and composition are what makes the asset the asset — edit those and you have a different asset, which may be what you want, but know that is what you did.
From your editor
Connect the MCP endpoint and skip the browser entirely — your agent searches the vault and reads prompts you have access to, in the editor you are already in.

Daily limits
Reading a prompt and downloading a file each count against a daily allowance: 5 prompts and 3 downloads a day on a free account, 50 prompts and 30 downloads a day on unlimited. Without an account you can read 1 free prompt a day and download nothing.
The window rolls: an allowance frees up twenty-four hours after it was spent, not at midnight. Browsing costs nothing — the item page only spends a read when you press Reveal the prompt. The same budget covers the website, the copy button on a library card and the MCP endpoint, so an agent and a browser draw on one pot.
These are here to stop a script taking the catalogue in an afternoon, not to ration real use. If you are hitting them doing ordinary work, that is a bug in the number — say so.
What you may do with the result
Use it in client work, modify it freely, keep it after cancelling. Do not resell the asset as an asset. That is the whole of it — the detail is on the licence page.
5 assets are free to any account, which is the cheapest way to find out whether the rest are worth it — each card says which. Browse the library.
