# Objective Move Bevy UI's rendering into a dedicated crate. Motivations: * Allow the UI renderer to be used with other UI frameworks than `bevy_ui`. * Allow for using alternative renderers like Vello with `bevy_ui`. * It's difficult for rendering contributors to make changes and improvements to the UI renderer as it requires in-depth knowledge of the UI implementation. ## Solution Move the `render` and `ui_material` modules from `bevy_ui` into a new crate `bevy_ui_render`. ## Testing Important examples to check are `testbed_ui`, `testbed_full_ui`, `ui_material`, `viewport_node` and `gradients`. --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>

## Cargo Features
|
|
|
|
Bevy exposes many features to customize the engine. Enabling them add functionalities but often come at the cost of longer compilation times and extra dependencies.
|
|
|
|
### Default Features
|
|
|
|
The default feature set enables most of the expected features of a game engine, like rendering in both 2D and 3D, asset loading, audio and UI. To help reduce compilation time, consider disabling default features and enabling only those you need.
