UI Builder

UI Builder lets you visually create and edit UI assets, such as UI Documents (.uxml), and StyleSheets (.uss), that you use with UI Toolkit.

Compatibility

As of 2021.1, UI Builder is now a core feature of Unity.

Accessing UI Builder

You can open the UI Builder window in two ways:

  1. Under the Editor window, select Window > UI Toolkit > UI Builder
  2. From the Project window, double-click a .uxml asset.

Optional dependencies

UI Builder has optional packages that offer additional functionality for creating UI for your game.

Vector graphics

You can install the com.unity.vectorgraphics package to have the UI Builder expose the ability to assign a VectorImage as a background style on an element.

2D Sprites support

You can install the com.unity.2d.sprite package to have the UI Builder expose the ability to assign a 2D Sprite asset (or sub-asset) as a background style on an element. With the 2D Sprite package installed, you will also have the ability to open the 2D Sprite Editor directly from the Inspector pane.
