# Set Paint Opacity

## Set Paint Opacity

This **Node** has different versions based on whether `Fill` or `Stroke` is set in the **Attributes**.

{% tabs %}
{% tab title="Fill" %}

### Overview

![The Set Fill Paint Opacity Node.](https://2561100106-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Ff6JZovzOqBctA4C1o76u%2Fuploads%2Fgit-blob-bb33baf10c9b1d51a5646e2ec51fc7caa1a76e43%2Fsetfillpaintopacity.png?alt=media)

The **Set Paint Node** sets the fill's `Opacity` -- meaning how opaque or transparent it appears -- of the selected **Object** at the specified layer indicated by the `Index`.

| `Index`   | **Int**      | Determines the layer of the fill content, if one is not provided in the **Input Socket**. It works in a top to bottom way, where 0 is the top layer and increasing layers are below it. |
| `Opacity` | **Float**    | How opaque or transparent the fill will appear, if no value is provided in the **Input Socket**.                                                                                        |

| *Pulse Input* (►) | **Pulse**    | A standard **Input Pulse**, to trigger the execution of the **Node**. |
| `Object ID`       | **ObjectID** | The ID of the **Object** that will have its fill's `Opacity` set.     |

{% tab title="Stroke" %}

### Overview

![The Set Stroke Paint Opacity Node.](https://2561100106-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Ff6JZovzOqBctA4C1o76u%2Fuploads%2Fgit-blob-a95c8eeff3dae909743987e76a068d7417553c74%2Fsetstrokepaintopacity.png?alt=media)

The **Set Paint Node** sets the stroke's `Opacity` -- meaning how opaque or transparent it appears -- of the selected **Object** at the specified layer indicated by the `Index`.
