[!CAUTION] in-progress crate.

Skein

A Bevy Plugin and a Blender extension for improving the efficiency of Bevy/Blender workflows.

tldr:

1. Register components in Bevy
2. Apply Bevy Components to objects, meshes, or materials in Blender
3. Export to glTF
4. Components are instantiated when spawning in Bevy

Quickstart

Add the plugin and register components (reflect(Component) is important!)

use bevy::prelude::*;
use bevy_skein::SkeinPlugin;

fn main() {
    App::new()
        .register_type::<Player>()
        .add_plugins((
            DefaultPlugins,
            SkeinPlugin::default(),
        ))
        .run();
}

#[derive(Component, Reflect, Debug)]
#[reflect(Component)]
struct Player {
    name: String,
    power: f32,
    test: i32,
}

• Install the Blender Addon (todo)
• Fetch the Bevy registry using the Blender Operator
• Select and apply a component
• Export to glTF
• Spawn a Scene from the glTF file, which will have components instantiated

commands.spawn(SceneRoot(asset_server.load(
    GltfAssetLabel::Scene(0).from_asset("my_export.gltf"),
)));

Use Cases

• Apply Bevy Components in Blender
• Replace materials from Blender with materials defined in Bevy (example)
• Use Blender Drivers to power Bevy Component values

Why is it named Skein?

Its a tool that aims to improve the efficiency of Bevy (group of birds) and Blender workflows.

A flock of wild geese or swans in flight, typically in a V-shaped formation.

• Oxford Dictionary

A V formation is a symmetric V- or chevron-shaped flight formation. In nature, it occurs among geese, swans, ducks, and other migratory birds, improving their energy efficiency

• Wikipedia

Its also thread/yarn related which is cool too.
