usd-convert-asset 1.0.0

Asset Converter that converts common asset file formats to OpenUSD

usd-convert-asset

Pip-installable package for usd-convert-asset.

This package is staged from the existing repo build output. The native bindings, runtime libraries, USD plugin resources, optional staged data, and generated third-party license bundle are copied into a wheel source tree under _build.

OpenUSD Runtime Compatibility

usd-convert-asset ships with and uses its own bundled OpenUSD runtime. Do not mix it with another OpenUSD or usd-core installation in the same Python process; competing pxr modules and native libraries can conflict.

If a workflow also uses other USD Python code, install the converter in a dedicated virtual environment and run conversion in a separate process. Invoke usd-convert-asset as a subprocess or use its CLI without importing both runtimes into one process.

Building From Source

Run the normal repo build first. This compiles asset_converter_native_bindings, copies runtime libraries into asset_converter_native_bindings/libs, generates PACKAGE-LICENSES, and stages the pip wheel source tree.

Windows:

.\repo.bat build --config release
.\repo.bat uv -- build _build\windows-x86_64\release\pip\usd_convert_asset -o dist

Linux x86_64:

./repo.sh build --config release
./repo.sh uv -- build _build/linux-x86_64/release/pip/usd_convert_asset -o dist

Linux aarch64:

./repo.sh build --config release
./repo.sh uv -- build _build/linux-aarch64/release/pip/usd_convert_asset -o dist

The wheel is written to dist/:

dist/usd_convert_asset-<version>-<python>-<abi>-<platform>.whl

Replace <version> with the version generated from VERSION.md. The wheel tag is inferred from the build interpreter and platform because the package contains native runtime libraries.

Testing From Source

Use a clean virtual environment and install the staged wheel or generated pip package directory. The package depends on native libraries staged by the repo build, so install from dist/ or _build/.../pip rather than from source/python directly.

Windows:

python -m venv .venv
.\.venv\Scripts\Activate.ps1
.\.venv\Scripts\python.exe -m pip install --upgrade pip
.\.venv\Scripts\python.exe -m pip install dist\usd_convert_asset-<version>-<python>-<abi>-<platform>.whl
usd-convert-asset -i path\to\input.fbx -o path\to\output.usda
.\.venv\Scripts\python.exe -m usd_convert_asset -i path\to\input.obj -o path\to\output.usdc

Linux:

python -m venv .venv
source .venv/bin/activate
.venv/bin/python -m pip install --upgrade pip
.venv/bin/python -m pip install dist/usd_convert_asset-<version>-<python>-<abi>-<platform>.whl
usd-convert-asset -i path/to/input.fbx -o path/to/output.usda
.venv/bin/python -m usd_convert_asset -i path/to/input.obj -o path/to/output.usdc

To test the staged tree before building a wheel, replace the wheel install with the generated pip package directory:

.venv/bin/python -m pip install _build/<platform>/<config>/pip/usd_convert_asset

Use the matching _build/<platform>/<config>/pip/usd_convert_asset path for the platform and configuration you built. Replace the input paths with existing source assets and the output paths with writable locations. Run usd-convert-asset --help for conversion flags such as --single-mesh, --ignore-materials, --fbx-y-up, and --progress.
