v0.12.2: Composable Scene

Jun 10, 2026

In v0.12.2, Scene exposes its render passes the way Pass and Renderer already do. A scene owns one ordered list of passes that you can read, append, remove, reorder, and replace, so a scene loaded from glTF composes on top of another pass in a frame instead of clearing it. Scene::load(...) is unchanged and still returns a renderable scene with sensible defaults. Scenes and the glTF loader arrived in v0.12.0.

What’s new

add_pass, remove_pass, get_pass, find_pass, list_passes, and set_passes read and edit the pass graph.
add_to puts a Model, Camera, or Light into a chosen pass by index or name.
Five methods decide whether the stock Camera and Light inject at first render: no_defaults, no_default_camera, no_default_light, set_default_camera, and set_default_light.
A pass reports its label through Pass::name.

Every method ships on Rust, Python, JavaScript, Swift, and Kotlin.

One behavior change

Passes render in list order. One added after the geometry now draws after it, while one added before it (the common backdrop case) is unaffected.

Release notes: GitHub v0.12.2.
