NRE — NVIDIA Omniverse NuRec (Neural Reconstruction Engine)

Purpose

Drive the public NVIDIA Omniverse NuRec / Neural Reconstruction Engine containers (nvcr.io/nvidia/nre/nre, nvcr.io/nvidia/nre/nre-tools) to train a 3DGUT/3DGRT Gaussian reconstruction from an NCore V4 camera+LiDAR clip, render novel views (locally or via gRPC), generate aux data, export PLY/depth/mesh/ego-mask/tracks, package Asset Harvester output into a USDZ, and evaluate rendering metrics.

This skill carries the host-side toolkit around the NRE CLI: NGC credential resolution, cached-image notes, local render recipes, MP4 encoding, warm serve-grpc boot/teardown scripts, a thin Python gRPC client for repeated RGB renders, bundled rig JSONs, pre-baked custom-rig trajectories, and bash / Hydra / OSMO workflow templates.
