Panic in naga/bevy_render: internal error: entered unreachable code on Apple M3 (macOS Sequoia) #22238
Description
Bevy version and features
- Bevy version: 0.16.1, 0.17.2, 0.17.3, 0.18.0-rc.1 (Reproduced on all these versions)
- Features: Default
Relevant system information
- Rust version: 1.89
- OS: macOS 15.7.1 Sequoia (Apple M3)
- Adapter Info:
AdapterInfo { name: "Apple M3", vendor: 0, device: 0, device_type: IntegratedGpu, driver: "", driver_info: "", backend: Metal }What you did
ran a minimal 3D scene setup
use bevy::prelude::*;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Startup, setup)
.run();
}
fn setup(
mut commands: Commands,
mut meshes: ResMut<Assets<Mesh>>,
mut materials: ResMut<Assets<StandardMaterial>>,
) {
commands.spawn((
Mesh3d(meshes.add(Plane3d::default())),
MeshMaterial3d(materials.add(Color::WHITE)),
));
commands.spawn((
Camera3d::default(),
Transform::from_xyz(0.0, 10.0, 0.0).looking_at(Vec3::ZERO, Vec3::NEG_Z),
));
}What went wrong
The application crashes immediately. If I comment out the MeshMaterial3d(materials.add(Color::WHITE)) line, the application runs normally without crashing (though the mesh is not visible or uses default error material). The crash only occurs when a material is assigned to the mesh.
