Digital Twin Troubleshooting#

This page consolidates troubleshooting information for Digital Twin components in Isaac Sim.

Warehouse Logistics Issues#

Warehouse Creator Issues#

  • If warehouse components don’t appear after generation, check for errors in the console logs

  • For layout issues, ensure the grid dimensions and spacing are properly configured

  • If textures appear incorrect, verify your material settings and check GPU compatibility

Conveyor Belt Issues#

  • For non-functioning conveyors, ensure the physics settings are correctly applied

  • If objects fall through conveyors, adjust collision settings and physics parameters

  • Animation speed issues can be resolved by checking the conveyor speed settings

Cortex Issues#

Decider Network Issues#

  • If decision networks fail to initialize, check that all required extensions are enabled

  • For unexpected behavior, review your network configurations and connections

  • Debug flows by enabling verbose logging and tracing through decisions step by step

Asset Loading Issues#

  • Missing assets can be resolved by checking file paths and ensuring assets are available

  • For slow loading of complex assets, consider using simpler versions for testing

  • USD file compatibility issues may require updating to the latest USD schema

Mapping Issues#

Occupancy Map Issues#

  • If occupancy maps fail to generate, ensure the scene has proper collision geometry

  • For inaccurate maps, adjust the resolution and sensor parameters

  • Missing areas in the map may indicate occlusion issues or raycast failures
