Conversion from USDZ file to glTF file

Updated: July 09, 2020.

Now USDZ to glTF conversion is possible...

At first, you need to install Autodesk Maya 2020 with Pixar Renderman 23.0.

Then unzip a USDZ zero-compressed archive to get a binary USDC (sometimes ascii USDA) file format and a set of textures. You need to import USDC into Maya. And if you need you can edit those PNG or JPG textures.

Unzipping a USDZ file in macOS...

• In macOS Finder change the suffix of USDZ file to ZIP.
• Uncompress ZIP file using Archive_Utility.app or RAR_Extractor.app.

• In Autodesk Maya (with pre-installed Renderman 23.0) import USDC model.
• Edit USDC model.
• Use Babylon exporter to produce a glTF format.
