What happened this week in the Bevy Engine ecosystem

Atmosphere Occlusion, Popover widgets, and window-breaking rendering

2025-11-03

Two interesting ECS PRs landed this week. One was a performance-related PR enabling dense iteration for FilteredEntity(Ref|Mut) in more cases and the other is pre-requisite work for Relationship-related query support: Support non-archetypal QueryData.

Improvements to testing infrastructure for FixedTimesteps, two new standard widgets, and more also landed.

The community comes through with a 1.5 year old 4x game, 4 player p2p networking, as well as more research-level work implementing new 2d lighting implementations and out-of-window rendering.

Atmosphere occlusion and PBR shading

Atmosphere

#21383 introduces the occlusion of directional lights by the atmosphere. Volumetric shadowing is supported through using FogVolume.

Easier FixedTimestep in Tests

#21705 introduces a new TimeUpdateStrategy that causes time to increment by the fixed timestep when calling app.update. This is useful when testing code that relies on a FixedTimestep.

// Now `app.update()` will run the fixed loop exactly once!
app.insert_resource(TimeUpdateStrategy::FixedTimesteps(1))

syn::Member in macros

#21678 cleans up macros by using syn::Member. This might be a good PR to check out if you're interested in authoring real world macros.

ImageLoaderSettings::array_layout

With TilemapChunk using 2d texture arrays, it is becoming more common for the ecosystem to use these textures. #21628 adds a setting to ImageLoaderSettings to enable this conversion at asset load time.

let array_texture = asset_server.load_with_settings(
    "textures/array_texture.png",
    |settings: &mut ImageLoaderSettings| {
        settings.array_layout = Some(ImageArrayLayout::RowCount(4));
    },
);

Standard Widgets: Popover and Menu

menu popover

#21636 adds a Popover and Menu widget to the experimental bevy_ui_widgets.

wayland popup

Outside of window rendering

showcase

This "out of window rendering" effect involved forking Bevy to pass parent windows on to winit, then forking winit to use the wayland popup API instead of the window API when it receives a request to create a wayland window with a parent.

Crates

New releases to crates.io and substantial updates to existing projects

Bevy Enhanced Input 0.19.1

crate_release

An input manager for Bevy, inspired by Unreal Engine's Enhanced Input.

0.19.1 introduces:

  • Combo input condition to bind a sequence of actions. You can use it for things like double-clicks or Vim-like shortcuts.
  • Pulse::with_initial_delay and Pulse::initial_delay to add a special delay before the first repeat. This can be used to implement key repeat.
