What's New in API v1 and v2 2026.2

Environment Variables

We added the environment variable, VRED_INSECURE_PYTHON. If you have struggled with Python Sandbox error messages, use VRED_INSECURE_PYTHON to overwrite the behavior of the Python Sandbox. Any value will disable the Python Sandbox. If VRED_SECURE_PYTHON is set, it will be ignored. VRED_INSECURE_PYTHON will override command line option and preference settings.

API V1

Some functions are in the VRED global namespace and can be called at any time without needing an instance of the class they are part of. Therefore, we added a "Global Functions" subheading for all functions without the need of a class instance.

We added these functions to the following classes in 2026.2:

In addition, the class documentation on top of the Ptr classes have a sentence now explaining this difference.

  • vrImagePtr - Moved createImage() → vrImagePtr to Global Functions. All other functions are listed under the Class Functions section.

  • vrLightLinkSetPtr - Moved createLightLinkSet, deleteLightLinkSet, findLightLinkSet, and getLightLinkSets to Global Functions. All other functions are listed under the Class Functions section.

  • vrMaterialPtr - Moved many functions to Global Functions. Added many functions to Class Functions. Moved removeAssetManagerReference under the Static Functions section.

  • vrNodePtr - Moved toNode and createLight to Global Functions. Moved removeAssetManagerReference` under the Static Functions section.

  • vrOSGWidget - Added a new variable, VR_DLSS_DLAA = 6, updated the setDLSSQuality parameters, and updated the getDLSSQuality return type documentation.

What's New in API v2 2024

This page shows what was added to and changed in the Python API v2 in VRED 2024, compared to 2023.4.

Python Version

The Python version was updated to 3.11.3.

  • VRED's Python version can be printed from within VRED with:
print(sys.version)

Qt Version

The Qt version was updated from Qt 5 to 6.2. This includes that the PySide module name changes from PySide2 to PySide6, and shiboken2 to shiboken6.

Note:

When option “Preferences > Script > Translate script to current Python version” is enabled, the names PySide2 and shiboken2 are automatically replaced by PySide6 and shiboken6 on the fly before executing Python scripts in VRED.

Porting Applications from PySide2 to PySide6

  • VRED's Qt version can be printed from within VRED with:
print(PySide6.QtCore.qVersion())

API

These are the new functions and classes:

  • vrGUIService.getViewCubeOpacity() → float

  • vrGUIService.getViewCubePosition() → vrGUIService.ViewCubePosition

  • vrGUIService.getViewCubeSize() → vrGUIService.ViewCubeSize

  • vrGUIService.isNavBarVisible() → bool

  • vrGUIService.isViewCubeVisible() → bool

  • vrGUIService.setNavBarVisible(value)

  • vrGUIService.setViewCubeOpacity(value)

  • vrGUIService.setViewCubePosition(value)

  • vrGUIService.setViewCubeSize(value)

  • vrGUIService.setViewCubeVisible(value)

  • vrHMDService.getActiveOpenXRRuntimeName() → string

  • vrHMDService.getActiveOpenXRSystemName() → string

  • vrHMDService.getOpenXRDepthLayerCompositionEnabled

  • vrHMDService.setOpenXRDepthLayerCompositionEnabled(enable)

  • vrMaterialTypes.MDL

  • vrMaterialTypes.MaterialX

  • vrRoughnessTextureTypes

  • vrdMDLMaterial

  • vrdMaterialXMaterial

  • vrdRoughnessTexture.getRoughnessMapType() → vrRoughnessTextureTypes.ValueMapping

  • vrdRoughnessTexture.setRoughnessMapType(mapping)

New Material Roughness

In VRED 2024, the material roughness is changed to a perceptually linear behavior and a new value range between 0 and 1. In older VRED versions, the behavior was non-linear and the maximum value was 40. When importing older files into VRED, material roughness values are automatically adjusted to the new behavior.

In case you set specific roughness values explicitly via script, for example with vrdPlasticMaterial.setRoughness(roughness), you must adjust the value in the script.

See this snippet for the conversion: snippets/convertRoughness.py.
