Kit 107.2 Release Highlights#

Release Date: April 2025

Kit SDK 107.2 is a significant update focused on improving performance, stability, and development experience for simulation and digital twin developers. This release includes enhanced simulation features and important updates to the RTX renderer.

Kit SDK#

Performance Improvements#

  • Added API for GPU-based transform hierarchy update

  • Reduce the overall CPU memory usage by 25% of a typical virtual factory scene that relies heavily on instancing, bringing FSD memory usage to be on par with OmniHydra

RTX Renderer Improvements#

Significant updates to the RTX renderer include:

  • Real-Time 2.0 Updates:

    • Better visual quality matching RTX Interactive mode

    • Now supported in movie capture workflows

  • New Camera Support: Added OpenCV Pinhole and Fisheye camera model support

  • Data Window Controls: New cropping and overscan capabilities

  • Enhanced Subsurface Scattering: Added new AOV support for better light path visualization

  • Smoother Material Transitions: Materials now maintain their previous appearance until new ones are fully loaded

  • Improved Denoising: Better quality for subsurface scattering materials and temporal denoising

UI/UX Improvements#

Several interface enhancements:

  • Asset Browser: Added support for connecting to S3 servers alongside existing Nucleus server connections

  • Unicode Name Normalization: Improves how special characters are handled in prim names.

    When renaming objects containing UTF-8 characters (like Korean Hangul components ᄀ and ᅡ), names are now automatically normalized to their canonical composed form (NFC) by default. This ensures consistent naming across your scene.

    • A notification will appear when normalization occurs

    • The normalization method can be toggled in Preferences > Stage

    • When disabled, UTF-8 characters remain in their original form

    • Duplicate normalized names are automatically handled with numbered suffixes (e.g., ‘_01’)

    This update helps maintain naming consistency while preserving flexibility for advanced workflows that require specific Unicode handling.

  • Schema Management UI:

    • New “Apply Schema” tool for quickly adding schemas to selected prims

    Edit API Schema

    • Visual indicators for applied schemas in the Property Window

    Schema API in Property Panel

  • Marquee Selection Improvements: Now supports selecting all prims within the selection box, including occluded objects

    Select Op

    • Area Select Occluded Objects Off

    Area Select Occluded Objects Off

    • Area Select Occluded Objects On
