- Arnold and MoonRay now require their own license features
- RenderMan now requires its own license feature; the descriptions of the last two features were expanded
- The licensing menu entry is shown in every locale and now has an icon
- Improved the activation dialog: failures are reported inside the dialog with the offending field highlighted, success closes it silently, and an attempt can be retried without closing it
Core
- USD layers on network shares are now read without memory mapping (detached layers), so an SMB hiccup no longer crashes the application with
STATUS_IN_PAGE_ERROR. The policy is configured inusd.detached_layers(policy:network/all/off, plusincludeandexclude) - Fixed a USEE crash when evaluating nodes after deactivating prims and groups
- Fixed the cursor sticking in the viewport during camera navigation and when closing panels
UV Editor
- Fixed selection: switching the prim in component mode no longer leaves the previous mesh selected
- Fixed UV shell moving: peak at high DPI, 16-bit color buffer, correct initial camera framing
- Curves and corrupted UV data no longer crash the editor: index checks, cache reset on UV set change and on scene change
Attribute Editor
- Significantly improved performance: lazy group construction, eliminated redundant re-evaluations, fixed caching, and more
- Improved appearance: new scrollbar, new panel header, fixed flicker when expanding groups, and more
Material Editor (Node Editor)
- Improved UX: better camera control, grouped shaders, better Tab search, improved connection handling, automatic Layout All
Render View
- Fixed scaling on high-DPI displays
- Fixed toolbar icon rendering
- Fixed cache-related crashes
Undo/Redo
- Fixed an error when deleting a relationship/connect in the Attribute Editor
Other
- Minor changes in the render delegate installation script
- The Expression toolbar now works with both PySide6 and PySide2
- Added property templates (as in Maya) and their display for the Attribute Editor and Material Editor
0.4.13.0August 31, 2026
Licensing
- The product now has a licensing system: without a valid license the application shows an activation dialog, and headless modes print the reason and exit with code 2
opendcc.wgen.*packages load only when the license carries theWGENfeature; the rest of the platform works as before- Plugins for Maya, Katana and Houdini without a license write a message to the log and do not load; the host application is unaffected
- The render farm and batch tools (
usd_render,scenelib_render,husk,katana --batch,mtoa) do not require a license - Activation methods: online by product key, offline via request/response text, license file import, and connection to a floating license server
- Added
floating_server— a floating license server supporting multiple products, with a Windows service and a systemd unit; if the connection is lost the application keeps working for another 30 minutes - Licensing dialog texts translated into all seven interface languages
- Trial and demo modes removed: a key means a license
