Crate bevy_render 

Useful Environment Variables

Both bevy_render and wgpu have a number of environment variable options for changing the runtime behavior of both crates. Many of these may be useful in development or release environments.

• WGPU_DEBUG=1 enables debug labels, which can be useful in release builds.
• WGPU_VALIDATION=0 disables validation layers. This can help with particularly spammy errors.
• WGPU_FORCE_FALLBACK_ADAPTER=1 attempts to force software rendering. This typically matches what is used in CI.
• WGPU_ADAPTER_NAME allows selecting a specific adapter by name.
• WGPU_SETTINGS_PRIO=webgl2 uses webgl2 limits.
• WGPU_SETTINGS_PRIO=webgpu uses webgpu limits.
• VERBOSE_SHADER_ERROR=1 prints more detailed information about WGSL compilation errors, such as shader defs and shader entrypoint.

The render prelude.

Macros

impl_atomic_pod

A macro that generates a blob type that allows a POD type to be updated in shared memory.

Structs

Extract

A helper for accessing MainWorld content using a system parameter.

Render

The main render schedule.

RenderApp

A label for the rendering sub-app.

RenderDebugFlags

Debugging flags that can optionally be set when constructing the renderer.

RenderPlugin

Contains the default Bevy rendering backend based on wgpu.

RenderScheduleOrder

Defines the schedules to be run for the rendering, including their order.

RenderStartup

The startup schedule of the RenderApp. This can potentially run multiple times, and not on a fresh render world. Every time a new RenderDevice is acquired, this schedule runs to initialize any gpu resources needed for rendering on it.

Enums

RenderSystems

The systems sets of the default App rendering schedule.

Traits

GpuResourceAppExt

Convenience methods for render-recovery-aware resource initialization.

Functions

get_adreno_model

If the RenderAdapterInfo is a Qualcomm Adreno, returns its model number.

get_mali_driver_version

Get the Mali driver version if the adapter is a Mali GPU.

get_pixel10_driver_version

init_gpu_resource

Constructs a T resource with from_world and inserts it.

storage_buffers_are_unsupported

Returns true if storage buffers are unsupported on this platform or false if they are supported.
