What Is Right vs What Is Wrong
| COMMON COMPETITOR ERRORS (WRONG) | BLUE PROJECTS GROUND TRUTH (RIGHT) |
|---|---|
| FAIL: Mismatched metric units causing 1000x scale errors when importing into PyTorch Sim2Real simulators | PASS: Explicitly declared `metersPerUnit = 1.0` metadata conforming to ISO metric standards |
| FAIL: Broken material bindings causing untextured grey meshes during GPU rendering | PASS: Standardized UsdPreviewSurface material bindings with relative texture asset paths |
