For test-specific information, please see the Graphical Test Overview.

--materialx --openimageio --build-args OpenImageIO,"-DOIIO_BUILD_TOOLS=ON" - Build guc in debug configuration, add it to your PATH
- Execute
run_tests.shusing bash
Test execution can be influenced using following variables:
| Name | Description |
|---|---|
| GT_DISABLE_CONVERSION | Disable glTF to USD conversion. This option reduces test execution time when debugging the MaterialX glTF PBR implementation or hdStorm. |
| GT_DISABLE_GRAPHICAL | Disable all graphical tests |
| GT_DISABLE_GRAPHICAL_MTLX | Disable MaterialX graphical tests |
| GT_DISABLE_GRAPHICAL_PREVIEW | Disable UsdPreviewSurface graphical tests |
| GT_VERBOSE | Print all executed commands |
Tests can be executed on the CI, via guc's GitHub Actions workflow.
Note: graphical test execution on the CI is not advised due to long execution times and rendering artifacts.
