A `STOP` button is available in the interface, allowing you to interrupt the execution of a function.

When preparing a model interactively in Asset Transformer Studio, some functions can take a long time to execute, especially when dealing with large models.

The user may wish to stop the execution of a function, because it is taking too long, or because they wish to change the parameters of the function before executing it again.

It is especially useful for time-consuming functions that are complex to parameterize and require step-by-step fine-tuning — like [Remove Occluded Geometries (Advanced)](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#removeoccludedgeometriesadvanced), [Orient Faces (Advanced)](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#orientpolygonfacesadvanced), or functions executing baking.

## How To

From the bottom right corner of the user interface, click the `STOP` button to interrupt a process.

A dialog box is then prompted asking you if you wish to confirm the interruption, choose `Yes` or `No`:

Enable the `Do not show again` option if you wish to stop being asked to confirm the interruption.

> **Note:**
>
> Not all functions can be stopped: the `STOP` button remains grayed out when interruption is not possible. For example, [importing a file](./importing-files.md) in Asset Transformer Studio cannot be stopped.
