Important Updates (2026.1)

There is a change to the Data Translator Toolkit, so please review this. Find information on this and the latest required Windows and Linux drivers, minimum requirements for VR/XR runtimes, and other changes in this article.

WARNING New Data Translator Toolkit

We have changed the preference default for the import toolkit from legacy to the new data translator. This forces the switching of the default toolkit, which could affect SolidEdge, SolidWorks, NX, Catia V4, and Catia V5 file import. The legacy version is scheduled for deprecation. Please report any translator toolkit issues experienced to Customer Support.

Drivers

For Windows users, the minimum NVIDIA driver required is v.551.23 or above, but an NVIDIA driver 553.62 is recommended for RGB raytracing and spectral raytracing.

Important:

At the time of release, driver versions between 555 and 570 were found to cause issues.

For Linux users, the minimum NVIDIA driver required is v.550.54 or above for RGB raytracing and spectral raytracing.

Codecs

For VRED 2026 and 2026.1, the OpenH264 v2.6 codec is the minimum requirement for VRED Stream. Download it here: https://github.com/cisco/openh264

VR/XR

For VR/XR, the minimum requirements regarding runtimes are as follows:

  • SteamVR 2.9.6 or newer for HMDs with SteamVR (OpenVR, OpenXR)
  • VarjoBase 4.7.0.9 or newer for Varjo HMDs with Varjo Base (Varjo native mode, OpenXR)
  • Meta Quest Link App 65.0.0.499.343 or newer for Meta/Oculus HMDs with Meta Quest Link App (OpenXR)
  • VIVE XR Elite requires VIVE Business Streaming v.1.15.11c and the VIVE Business Streaming App v.1.0.21.14

Constraints

We improved the constraints system behavior for Use Maintained Offset and updated the default settings for the new orientation constraints.

Important:

These changes to the constraints system behavior may affect existing scripts, as the the default coordinate system for orientation constraints changed from "world-to-world" to "object-to-object".

  • OpenColorIO was updated to 2.4.2
  • MDL SDK was updated to 2024.1.1
  • DLSS was updated to 310.2.1
