Bevy 0.10 Res<AssetServer>::load(...) Causes Panic Given Valid Path

[asb9189]

Bevy version

0.10

[Optional] Relevant system information

Rust version: cargo 1.68.1 (115f34552 2023-02-26)
OS: macOS Ventura 13.2.1
AdapterInfo { name: "Apple M1", vendor: 0, device: 0, device_type: IntegratedGpu, driver: "", driver_info: "", backend: Metal }

What you did

I created a simple Bevy project and added an 'assets' directory that is a sibling of the 'src' directory. The structure is as follows:

• ROOT
  • assets
    • Idle.png
  • src
  • target

What went wrong

A panic occurs when trying to fetch the "Idle.png" using asset_server.load("Idle.png"). Unfortunately, I am unable to make sense of the stack trace and haven’t been able to find anything else about this issue online.

• what were you expecting?

I would expect the application to run (without crashing) and display my Idle.png (44x47) in the center of the screen.

• what actually happened?

panic occurs during startup_system

Additional information

Project code:

use bevy::prelude::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_startup_system(setup)
        .run();
}

fn setup(
    mut commands: Commands,
    asset_server: Res<AssetServer>,
) {
    
    commands.spawn(Camera2dBundle::default());

    commands.spawn(SpriteBundle {
        texture: asset_server.load("Idle.png"), // Causes panic
        transform: Transform::from_translation(Vec3::new(0., 0., 0.)),
        ..default()
    });
}

Hmm, that's not a very useful error message at all. It looks like your asset isn't being processed properly.

16-bit pngs are not supported currently. See #7005

[asb9189]

Does the Bevy team plan on supporting 16-bit pngs in the near future? Is there anything I could be doing/using to use my pngs in the meantime? @devil-ira

The project I'm working on relies on a several 16-bit pngs.
