Changelog

0.4.13.1September 10, 2026current

Wgen

  • Fixed spurious duplication of modifiers in the Wgen Outliner panel

Other

  • Fixed the style of the disabled button
  • Updated the appearance of the slider with tick marks

Licensing

  • Added the dcc_license command-line utility for license activation
  • Removed the disconnect and activation buttons in floating mode
  • 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 in usd.detached_layers (policy: network/all/off, plus include and exclude)
  • 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 the WGEN feature; 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

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
