# Reuse and trace a result

> Run a result again with its exact settings, and see what it was made from and what's been made from it.

Every result in Generate remembers how it was made. Use that to run it again
with one change, or to follow it back to the files it started from.

## Reuse a result's settings

**Reuse parameters** puts a result's model, prompt, settings and references
back into the generator, so you can change one thing and generate again.

Hover over a result in **Generations** and choose the **Reuse parameters**
button, the circular arrows. It's also in the viewer's actions when you open a
result.

The generator fills in:

* The model.
* The prompt, with its `@` references in place.
* The references, start and end frames, and keyframes the result used.
* Its output settings, such as aspect ratio, resolution, duration, sound or
  voice.

Nothing runs until you choose **Generate**, so check **Cost** first. To start
over, choose **Clear prompt and references**, the reset button at the top
right of the generator.

To add a result to your next generation as a reference or frame instead, see
[Use as a reference or frame](https://docs.zerogen.com/generate/frames-and-references.md#use-as-a-reference-or-frame).

### When a result can't be reused

Generate tells you why instead of loading it. The most common reasons:

* The result is the 1080p upscale of a Seedance draft. Reuse the draft
  instead. See [Draft, then upscale](https://docs.zerogen.com/generate/draft-then-upscale.md).
* One of its references has been deleted or is no longer available.
* It used a model, setting or input that Generate no longer offers, or it was
  made with an earlier version of Generate.

## See what a result was made from

Open a result in the viewer and choose **Show reference graph**.

The uploaded photos are blurred.](https://mintcdn.com/zero-gen/m4I7fPs1rAXZSMjU/images/generate/reference-graph.png?fit=max\&auto=format\&n=m4I7fPs1rAXZSMjU\&q=85\&s=4cacb5f6a39b26298ad63ffe4735fbb2)

What the result was made from is on the left, what's been made from it is on
the right, and the result you opened is marked **This asset**. To read and move
around the graph, see
[Reuse and trace an asset](https://docs.zerogen.com/library/reuse-and-trace.md#read-the-graph).
