Issue with “Import URDF” Tutorial (Collision Mesh Visualization)

[eastseaking]

Description

Hello,

I am currently following the official tutorial at the link below:
https://docs.isaacsim.omniverse.nvidia.com/5.1.0/importer_exporter/import_urdf.html#isaac-sim-app-tutorial-advanced-import-urdf

While working through the “Direct Import” section—specifically the “Visualize the collision meshes” step—I found that the collision meshes are not being displayed.

To verify whether collision geometry exists, I created a cube with rigid body enabled above the robot and dropped it during simulation. The cube clearly collides with the robot, so collision seems to be active, but the collision meshes still do not appear visually.

Are there any specific settings or checks required to make collision meshes visible?

Thank you.

The URDF importer seems to have some bugs; it might be better to manually configure the collider properties.

Thank you. I'll try that.
