A sample workflow implementation to aide in the conversion of Cinema 4d files to iOS Quicklook USDZ 3D files.

• /spinner/spinner.c4d is the Cinema 4d 3D source file which is used to bake textures and export to other formats.

• /spinner/tex contains the source images for texture maps referenced by that file.

• /spinner/baked contains the 'baked' textures for each of the various PBR channels.

• /spinner/abc: Alembic (export settings)
• /spinner/dae: Collada (v1.4, everything unchecked)

• /spinner/gltf: glTF (uncompressed)
• /spinner/glb: glTF (binary)
• /docs/usdz: Universal Scene Description (Zipped)

• /spinner/mkargs, is a bash script that will automatically generate a /spinner/usdargs.txt file which can be passed into the apple usdz_converter tool via the -f argument.

In order to open the 3D source file, you will need to install Cinema 4d. This file was created with R20.

To create a USDZ file, I converted the exported Alembic file using usdz_converter. usdz_converter is a utility that comes with Xcode. An introduction to that tool (not quite documentation), can be found in this WWDC 18 video.
