Struct SceneImport 

pub struct SceneImport {
    pub source: String,
    pub texture_max_size: u32,
    pub emissive_map_strength: f32,
    pub emit_camera: bool,
}

Imports a 3D scene file as a single declaration.

One SceneImport stands in for the whole asset graph a scene file describes: its Textures, Materials, Meshes, Models, and Props. The build expands the import into those concrete assets, so world.jsonl stays small and human-editable while the full graph lives in the lock file and compiled blob. Geometry and texture pixels are never inlined into world.jsonl.

Supported source formats: .fbx and .glb.

Generated names are prefixed with the import’s own asset name (<name>_mat_0, <name>_prim_0, <name>_model_0, …), so they never clash with hand-authored assets. Because they only appear in the lock file and blob, you never reference them by hand.

Camera: the import frames a Camera3D to the scene’s bounds so a freshly imported scene is immediately viewable. It is suppressed when the world already declares a Camera3D (yours wins) or when emit_camera is set to false.

SceneImport {
    source: "assets/Bistro/BistroExterior.fbx".into(),
    texture_max_size: 512,
    ..Default::default()
};

Fields

source: String

Path to the scene file, relative to the project root. .fbx or .glb.

texture_max_size: u32

Ceiling on the longest edge of each imported texture, in pixels. Large source maps (2K-4K) are box-filtered down so the compiled scene, which stores uncompressed pixels, stays within a sane memory budget. 0 keeps each texture at its source resolution.

emissive_map_strength: f32

Emissive factor applied to a material that carries an emissive map. Scene files often ship a zero emissive factor that would cancel the map, so a textured emissive gets this punchy factor instead.

emit_camera: bool

Whether to emit a Camera3D framed to the scene’s bounds. Suppressed automatically when the world already declares a Camera3D.
