What AI says about gltfpack

gltfpack is a command-line tool from meshoptimizer that automatically optimizes glTF/GLB files to reduce download size and improve loading and rendering by optimizing meshes, quantizing geometry, merging meshes, simplifying animations, and pruning the node tree. It can also compress textures (BasisU via KTX2 or WebP) and emit compressed outputs that require loader support for EXT_meshopt_compression. Installable as pre-built binaries or via npm, it also handles point clouds and uses a WebAssembly meshopt_decoder for client-side decompression.
