# Replace a specific material

> Swap one material in a finished render with a short, single-change prompt

To try a different material on a finished render, describe just that one change. A short prompt that names the element and the new material keeps everything else the same.

## How it works

1. **Render to edit** holds the finished image.
2. **Swap podium brick (Muse)**: *Change the red-brown brick of the three-storey podium to a pale cream glazed brick with fine light-grey mortar joints.*

## Tips

* Change one material per run. Several changes in one prompt drift further from the original.
* If other parts of the image change too, use a mask ([masks by material](https://docs.runchat.com/examples/masks-by-rhino-material.md)) to lock them.
