With Bevy 0.9 cameras can render to HDR textures. I tested this with the code on master and the app crashed.
Here is the error:
thread 'main' panicked at 'wgpu error: Validation Error
Caused by:
In a RenderPass
note: encoder = `<CommandBuffer-(0, 1, Vulkan)>`
In a set_pipeline command
note: render pipeline = `shape_pipeline`
Render pipeline targets are incompatible with render pass
Incompatible color attachment: the renderpass expected [Some(Rgba16Float)] but was given [Some(Rgba8UnormSrgb)]
This is caused by the target color texture format being hard coded as TextureFormat::bevy_default(). I changed the hard coded value to Rgba16Float in a local clone of this repo and it fixed the problem, but obviously would cause crashes for none HDR cameras.
Unfortunately I'm not familiar enough with the Bevy render pipeline to figure out how to determine the correct format at runtime. I believe you would have to specialize the mesh2d pipeline but I don't know how. It might be easier to replace the current rendering implementation with one of the newer high level material APIs.
