  • OM-Improved performance when framing objects by pressing F in viewport.

  • OM-Fixed std::bad_weak_ptr exception on several omni.kit.ui python bindings.

  • OM-Fixed “Create Camera from View” only taking the local transform of the source camera.

UI Framework

  • New UI toolkit called Omni::UI to enable extendable and visually compelling user interfaces.

  • Omni UI Components: Dynamic layout system, Flexible styles, Button, Image, Label, Model based widget like ColorWidget, Slider, ComboBox, ToolButton.

  • Advanced UI element for Tree, List Views using fast and flexible models.

  • Workspace system to control Kit’s windows and docking.

  • Streaming Widget extension.

  • New Web component based on chrome to create web content views and based interfaces.

  • Previous python UI system is still present but will be deprecated over the next couple of versions.

  • Stage View re-implemented using Omni::UI in with Python.

Kit Application UI/Material Workflow

  • OM-Status bar now displays the last logging message at bottom left corner.

  • OM-Support to drag and drop materials from stage window to viewport window to enable binding of material.

  • OM-Context menu support using Right click in Layer, Stage and Viewport Windows.

  • OM-New Scene Presets and options to create your own.

  • OM-New Selection workflow to Select All, None, Inverse, Hide, Unselect etc.

  • OM-Viewport HUD stats on/off.

  • OM-Viewport Display Purpose menu.

  • OM-Viewport Display By Type menu.

Cloud and Microservices

  • OM-New Control Port extension to write micro-services for Kit.

  • OM-New Kit agent extension to enable to launch Kit instance remotely.

Streaming

  • OM-Created an Omniverse Kit Remote installer.

  • OM-Client streaming window is now resizable, Kit must be launched with –carb/app/livestream/allowResize=true to enable the feature.

  • OM-Windows clients are now launched automatically when a URL beginning with kit-remote-2020-1:// is present. For instance, kit-remote-2020-1://127.0.0.1 would launch Omniverse Kit Remote and automatically attempt to connect to a streaming Kit server on localhost.

  • OM-Allow High DPI sessions in Omniverse Kit Remote with the -d command line parameter.
