USDZ files generated by the command line/python tools seem to be 30-50% larger than those generated by RealityConverter. Any chance we'll see some updated USDZ command line tools soon? Processing large volumes of files through RealityConverter is a bit painful, but worth the effort on mobile.
Hi, can you share the file you are converting with the tools, along with what versions of the tools you are using?
This version of USD Python tools uses Python 3.7. You can download and install Python 3.7.9 (recommended) from
usdzconvert (version 0.66)

Reality Converter vs 1.0 (53)
The smallest I can get the USDZ file output is from RealityKit @ 1.5mb. Other methods output 4mb+, including USDZ tools and Blender 3.5. I imagine Reality Kit is performing some automated optimizations, but it would be nice to know what they are, and how to get these smaller sizes from the command line.
