bevy_vulkano

This plugin replaces core loop & rendering in bevy with Vulkano backend. Currenlty you can only use it for a single window.

Provides a Renderer to organize target images and exposes an api to start_frame and end_frame. However, you'll have handle rendering yourself in between. Resizing is handled as well. Provide your own camera though.

See example circle for how to use this.

  1. Add VulkanoWinitPlugin. You'll need bevy's WindowPlugin
  2. Then create your own rendering systems using vulkano's pipelines (See example.). You'll need to know how to use Vulkano.
  3. If you want to use egui library with this, add egui_winit_vulkano & egui to your dependencies and bevy_vulkano with feature gui
