Bringing 3DGS into NVIDIA Isaac Sim: A Photoreal Import Workflow and Four Industrial-Simulation Weaknesses

How to import 3DGS scans into Isaac Sim 6.0: the silent 2^24 point cap, USD conversion, orientation fixes, trajectory cameras — plus four industrial weaknesses and mesh-based workarounds.

Setting Up a 3DGS Simulation Environment for Isaac Sim: Untouched Scan Data, Ground-Hole Patches, and a PhysX Vehicle in Three Steps

Using Shibuya's scramble crossing as a case study: keep the scanner's 3DGS and mesh untouched, patch only the ground holes from measured LiDAR, stack appearance and physics as two layers, and drive a PhysX Vehicle in Isaac Sim.
