# Objective In our project we parse `GltfNode` from `*.gltf` file, and we need extra properties information from Blender. Right now there is no way to get this properties from GltfNode (only through query when you spawn scene), so objective of this PR is to add extra properties to `GltfNode` ## Solution Store extra properties inside `Gltf` structs --- ## Changelog - Add pub field `extras` to `GltfNode`/`GltfMesh`/`GltfPrimitive` which store extras - Add pub field `material_extras` to `GltfPrimitive` which store material extras
