A small Python-based OpenUSD pipeline utility that demonstrates how to:

• load USD stages programmatically
• inspect and traverse prims
• modify prim attributes
• adjust transforms
• author material-based variants
• export new USD artifacts

This project moves beyond using Omniverse or Isaac Sim interactively and demonstrates programmatic USD pipeline control in Python.

It is designed to show recruiter-relevant OpenUSD engineering skills for Digital Twin, simulation, and robotics workflows.

• Create a sample USD stage
• Load an existing USD file
• Inspect stage prims
• Modify /World/MyCube
• Change cube size and translation
• Author a color variant set with:
  • blue
  • red
• Verify variants programmatically
• Export processed USD files into output/

Create a fresh sample stage and process it:

python3 src/pipeline_tool.py --input-stage fresh_demo.usda --create-sample

**Process an existing stage:**

python3 src/pipeline_tool.py --input-stage recruiter_demo.usda

The tool generates outputs such as:

*_modified.usda *_with_variants.usda

The tool authors a color variant set on /World/MyCube and preserves authored variant structure by exporting the root layer rather than flattening only the composed stage result.
