Created a comprehensive environment for comparing TinyUSDZ with OpenUSD: - Setup scripts for building OpenUSD with Python bindings using clang-20 - Python comparison script (compare_usd_example.py) for testing both libraries - C++ build examples using both Makefile and CMake - Example C++ code that loads USD files with both libraries - Comprehensive documentation for setup and usage The environment allows side-by-side comparison of USD file parsing, metadata extraction, and scene traversal between TinyUSDZ and OpenUSD. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
