How to actually run any bevy example using OpenGL?

[dmitrykolesnikovich]

I tried to change VULKAN to GL in window.rs file but without effect

Hi! That's not how you do it. You can change the backend by setting the backends field of the WgpuSettings in the RenderPlugin.
Here's the example:

bevy/examples/app/no_renderer.rs

Line 17 in 56c3079

backends: None,

You can also set the WGPU_BACKEND=GL (iirc it's GL) environment variable. Keep in mind, I would not use opengl unless you have to. Not all features will be supported.

It seems like GL not supported

Unable to find a GPU! Make sure you have installed required drivers!
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Can confirm that this still happens for me

I think to use OpenGL:

Enable the gles feature in the bevy_render crate.

bevy_render = { version = "0.19.1", features = ["gles"] }

Enable it in the code:

DefaultPlugins.set(RenderPlugin {
    render_creation: RenderCreation::Automatic(Box::new(WgpuSettings {
        priority: WgpuSettingsPriority::WebGL2,
        limits: WgpuLimits::downlevel_webgl2_defaults()
            .using_resolution(WgpuLimits::default()),
        backends: Some(Backends::GL),
        ..default()
    })),
    ..default()
})

Maybe also .disable::<PbrPlugin>())
