-o, --output	output/${input}.gltf	No	Path to the output glTF file
--basepath	Parent of input path	No	Resolve external uris using this as the reference path
-s, --separate	false	No	Output separate binary buffer, shaders, and textures
-t, --separateTextures	false	No	Output textures separately
-b, --binary	false	No	Output Binary glTF
-m, --materialsCommon	false	No	Output materials using the KHR_materials_common extension
-v, --version		No	glTF version to output (e.g. '1.0', '2.0')
-d, --dracoCompression	false	No	Output meshes using Draco compression extension
--qp		No	Quantization bits used for position attributes in Draco compression extension
--qn		No	Quantization bits used for normal attributes in Draco compression extension
