FigmaToUnity is a specialized Unity tool that streamlines the UI development process by enabling the direct import of Figma page documents into Unity. The tool automatically converts Figma designs into UI Toolkit assets, allowing for quick and accurate integration of UI interfaces into your Unity games.
Name | Description |
---|---|
Figma Import to UXML/USS | The tool imports and parses Figma page documents, transforming them into UXML and USS assets within Unity. |
Element Manipulation | Enables the manipulation of UI elements and the application of custom logic via Unity scripts, providing extensive control over the user interface. |
Sync Changes | Changes made to UI elements in Figma can be readily fetched and updated in Unity, maintaining the integrity of the game's UI. |
Limitations | Refer to the section below. |

The token is stored in raw format.
- Visit the Figma API Authentication Page.
- Click + Get personal access token to generate the token.
- Copy the generated token.
- Locate the Figma script in Unity's Inspector.
- Paste the token into the designated field.

Working with this plugin is done through using Figma component inspector FigmaInspector. In addition, components derived from the Element class should be created and added to the same GameObject hierarchy. These components serve a dual purpose:
- During the import phase, they assist in filtering and configuring various aspects of the document, such as frame selection and image handling.
- During runtime, they provide the functionality to manipulate UXML and USS data structures.
Property | Description |
---|---|
Panel Settings | A crucial asset enabling Unity to render UXML-based user interfaces within the Game View. |
Source Asset | The UXML asset responsible for outlining the structural framework of the user interface. |
Sort Order | Specifies the rendering sequence of UXML assets when multiple Panel Settings instances exist within a project. |
Title | Designates the title from the Figma document URL for identification purposes. |
Asset | Represents the UXML asset correlating with the corresponding asset within the UI document script. (Refer to the section above for further details) |
Update Buttons | Facilitates UI updates, offering options to include or exclude the downloading of all associated images. |
De-root and Re-order Hierarchy | Adjusts the organization of all frames based on each element's RootOrder property, optimizing the UI hierarchy. |
Filter by Path | When activated, this feature limits the download to only those UI frames that have associated scripts attached to the prefab, otherwise, all UI elements within the Figma document will be downloaded. |
Additional Fonts Directories | Provides the capability to specify paths to any fonts that are incorporated within the UI, ensuring seamless visual consistency. |
During the update process the Figma class retrieves data based on the Uxml and Query attributes of the Element scripts. It then utilizes this data while producing UXML asset.
Warning
Element scripts should be attached to the same game object to which the Figma script is also attached.
The Uxml and Query attributes define the structure of the Uxml asset and, consequently, the appearance of your UI. The type of the field following the Query attribute defines the UI element itself and, consequently, its behavior (VisualElement, Button, Label, etc.). Field types are written into UXML. Therefore, if you change the field type (for example, from VisualElement to Button), you will need to perform a Figma Update to regenerate the UXML. Each element can override OnInitialize and OnRebuild methods which can be used to do any initial setup operations.

This interface serves as an identifier, signifying that within the IRootElement hierarchy, an element exists which can function as a component based on the VisualElement class.
This interface acts as a marker, indicating that an element within the IRootElement hierarchy is capable of functioning as a component derived from the VisualElement class.
The imported USS file contains all the classes used by Visual Elements. USS is inspired by CSS and has a similar syntax. To manipulate properties in your code, you should use the techniques described below.
To change the appearance of a VisualElement, you should manipulate its style properties. For example, to set the top margin of an element to 3:
element.style.marginTop = 3;
If you need to read style data from a VisualElement, you should use its resolved style properties. For example, to retrieve the value of the top margin:
float margin = element.resolvedStyle.marginTop;
You can find the list of all supported properties in the official Unity documentation.
When working with VisualElements, there are various visual element extensions that allow you to find/clone/replace/etc elements:
VisualElement rectangle = element.Find<VisualElement>("Rectangle");
VisualElement elementClone = options.Clone();
element.Replace(newElement);
Feature | Description |
---|---|
Unique Frame Names | Each frame must have a unique name to ensure proper functionality. |
Vector Constraints | Vectors should be visible, should not contain Image Fills, and, where possible, should be grouped into Unions. |
Fill Limitations | Each UI element can contain only a single Fill attribute. |
Auto-Layout Restrictions | Stroke borders are not supported within Auto-Layout configurations. |
Alignment Constraints | Horizontal and vertical centering cannot be mixed within the same parent element; doing so will default the alignment to center-center. |
Circle Representation | For optimal visual rendering, circles should be implemented using rectangles rather than ellipses. |
