GLTFMesh handles 3D mesh data imported from glTF files. It includes properties for blend channels, blend weights, instance materials, and the mesh itself.
Gets additional arbitrary data in this [GLTFMesh] instance. This can be used to keep per-node state data in [GLTFDocumentExtension] classes, which is important because they are stateless.
The argument should be the [GLTFDocumentExtension] name (does not have to match the extension name in the glTF file), and the return value can be anything you set. If nothing was set, the return value is [code]null[/code].
Sets additional arbitrary data in this [GLTFMesh] instance. This can be used to keep per-node state data in [GLTFDocumentExtension] classes, which is important because they are stateless.
The first argument should be the [GLTFDocumentExtension] name (does not have to match the extension name in the glTF file), and the second argument can be anything you want.
