Options

Flag Default Required Description
-i, --input Yes Path to the input COLLADA file
-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
--qt No Quantization bits used for texcoord attributes in Draco compression extension
