General Improvements
We’ve exposed vrLogService to set a log level, added more updates to the Substance and MDL SDKs, and DLSS and MaterialX versions, plus much more.
Video captions: Another third-party update is the new Substance SDK, which we implemented to support the latest Substance node types, such as splines scatter nodes for example, like this one, which generates stitches following a path around the embossed patterning. And, I can easily change the complete inputs for it. This gives you so much more flexibility in your CMF workflow.
Log Levels
We have exposed vrLogService to add a log level to a Python request. Choose from:
- info(message, context): This is the least restrictive. Everything (info, warnings, and errors) is displayed.
- warning(message, context): This is medium restrictive. Only warnings and errors are displayed.
- error(message, context): This is the most restrictive. Only errors are displayed.
Updates
Updated the MDL SDK to version 2023.1.4.
Updated MaterialX to version 1.38.9.
Updated the Substance SDK to version 9.1.2 to support newer Substance node types such as Spline, Spline Scatter, and Crop Node. Use it for generating stitches following a path around the embossed patterning. Easily change the complete inputs. This can give you much more flexibility in your CMF workflow.
Updated the DLSS to version 3.7 for alpha channel support for backplates or mixed reality when raytracing.
2025 2025.1 
Encrypted HTTPS Only
The option, Encrypted HTTPS Only, can now be set using the system variable, VRED_FORCE_HTTPS.
When
VRED_FORCE_HTTPSis set to 1, Encrypted HTTPS Only is enabled, redirecting incoming unencrypted (http) connection requests to encrypted (https) connection requests in the VRED web interface. Encrypted HTTPS Only is greyed out in the preferences and cannot to changed through the UI.When
VRED_FORCE_HTTPSis set to 0, VRED uses the Encrypted HTTPS Only preference option setting.
Remove Preview
We added Remove to the Variant Sets context menu to delete variant set thumbnail preview. Either select a preview from the tree or in the Variant Set Simple View Mode, right-click, and select Preview Image > Remove to remove the selected preview from the set.
Updated VRED_DISABLE_ADP
The description for the environment variable, VRED_DISABLE_ADP,changed to the following:
Any value: Disables the Autodesk data collection feature.
Starting with VRED 2025, ADP can be disabled machine wide by creating a new registry key HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\Privacy\TrustLevel (string value) with a value of 1.
Online Help Updates
You will find we re-organized the VRED Python Examples, making it much easier to find specific examples.
