Layer 3d orthographic camera over 2d camera | Bevy | Page 1

I've been trying to get a 2d particle system to work with a 3d rendered orthographic view to no avail.
Anyone have any ideas on how this is supposed to work?

commands.spawn(Camera3dBundle {
        camera_3d: Camera3d {  ..default()},
        camera: Camera {priority: 1, ..default()},
        projection: Projection::Orthographic(OrthographicProjection {
            scale: 0.05,
            ..default()
        }),
        transform: Transform::from_xyz(0.0, 0.0, 999.0).looking_at(Vec3::ZERO, Vec3::Y),
        /*transform: Transform::from_xyz(0.0, 0.0, -30.0).looking_at(Vec3::ZERO, Vec3::Y),*/
        ..default()
    })

#

Note, I think my setting the orthographic scale to 0.05 is making it difficult to line up views, but my 3d models are absolutely tiny without changing scale

Instead of changing scale, why not move the models closer or scale them up?

RenderLayers in bevy::render::view - Rust

Describes which rendering layers an entity belongs to.

#

Also, RenderLayers might be what you want (this works for 3D, but I haven't tried it for 2D + 3D)

Reverting scale does not seem to get 2d and 3d to work correctly

#

I think my 3d orthographic camera is clipping too close by?
