Release Notes — Version 26.03#

April 2026#

Core Improvements

  • gRPC Local Scene Registration: The x-nre-scene-url header now accepts local file URIs for on-the-fly scene registration. When a local path is provided, the scene is registered directly without downloading, and local scene artifacts are preserved across requests.

  • Aux Gen Per-Camera Ego Mask: Auxiliary data generation now supports per-camera ego mask generation, enabling more granular control over ego vehicle masking across camera setups.

Bug Fixes

  • gRPC Asset Editing: Fixed multiple issues with asset editing via the gRPC API: local PLY file paths are now supported for asset insertion; asset insertion gating and state restoration are handled correctly; partial asset edits are now rolled back on replace or insert failure; and edit asset replacement handling is fixed.

  • LiDAR Rendering Quality: Fixed a regression where Gaussians smaller than the dense tile size were incorrectly culled during LiDAR rendering, causing a 2x artificial training speedup and minor quality drop. Rendering now behaves consistently with pre-regression behavior while retaining all prior bug fixes.

  • Dynamic Object Classification: Fixed a bug where vehicles behind the ego vehicle were misclassified as static when no camera-visible intervals existed for those tracks. The classifier now falls back to full track poses in that case.

  • Asset Harvester FOV: Fixed an incorrect field-of-view calculation in Asset Harvester object view extraction.
