How do I tell bevy which rendering backend should it use? My app starts with vulkan backend and crashes with access violation, I want to try switching to dx12 and see if it helps

I had something not too disimilar where I had to force it be vulkan otherwise it wouldn't start:

add_plugins(DefaultPlugins.set(RenderPlugin {
    render_creation: RenderCreation::Automatic(WgpuSettings {
        backends: Some(Backends::VULKAN),
        ..default()
    }),
    ..default()
}))

You can probably change it to your needs

Thanks man! This helped, indeed setting it to vulkan explicitly solves the crash. This is not ideal , but unblocks me :🎉

It should be using vulkan automatically if you're on windows/linux.

#

If it's not, that's probably a bug in wgpu

the thing is : I'm not sure. From the logs it seems like it's using vulkan, but it's crashing for some reason. After setting vulkan explicitly the problem goes away.

Defeinitly shouldn't be happening. Try the wgpu examples and see if you can reproduce there, and report a bug to them.
