Usage

See the crate documentation for example usage.

Features

Extras and names

By default, gltf ignores all extras and names included with glTF assets. You can negate this by enabling the extras and names features, respectively.

[dependencies.gltf]
version = "1.2"
features = ["extras", "names"]

glTF extensions

The following glTF extensions are supported by the crate:

• KHR_lights_punctual
• KHR_materials_pbrSpecularGlossiness
• KHR_materials_unlit
• KHR_texture_transform
• KHR_materials_variants
• KHR_materials_volume
• KHR_materials_specular
• KHR_materials_transmission

To use an extension, list its name in the features section.

[dependencies.gltf]
features = ["KHR_materials_unlit"]

cargo run --example gltf-export

gltf-roundtrip

Deserializes and serializes the JSON part of a glTF asset.

cargo run --example gltf-roundtrip path/to/asset.gltf
