RViz2 (humble) crashed due to lack of GLSL 150 files in Isaac ROS container

[MyDearestJingo]

Problem description

For latest release-3.2 version , package ros-humble-rviz-rendering version (11.2.23) which Isaac ROS container chooses when building has removed glsl150 shader definitions. This change caused RViz2 crashed when running the example of Nvblox and visualizing with nvblox_rviz_plugin.

[rviz2-3] [ERROR] [1767498240.394272445] [rviz2]: ItemIdentityException: Unable to locate geometry program called rviz/glsl150/box.geom. in GpuProgramUsage::_getProgramByName at ./.obj-x86_64-linux-gnu/ogre-v1.12.1-prefix/src/ogre-v1.12.1/OgreMain/src/OgreGpuProgramUsage.cpp (line 92)

Environment

	Version
Host OS	5.15.0-139-generic #149~20.04.1-Ubuntu
GPU and driver	RTX 4090-D and 570.86.16
Isaac ROS	3.2
Isaac ROS common	3.2
Isaac ROS Nvblox	3.2
ros-humble-rviz-rendering	11.2.23-1jammy.20251108.015125
ros-humble-rviz2	11.2.23-1jammy.20251119.020146
OpenGL version	4.6.0 NVIDIA 570.86.16

Solution (bad option)

Just replace the directory /opt/ros/humble/share/rviz_rendering/ogre_media/meterials/rviz_rendering/ogre_media/meterials in the container with the one of version 11.2.22 which can be found at RViz repo or ROS Humble official Docker image.
Before (in container):

$ls /opt/ros/humble/share/rviz_rendering/ogre_media/meterials
glsl120  scripts  scripts120

After:

$ls /opt/ros/humble/share/rviz_rendering/ogre_media/meterials
glsl120  glsl150  scripts  scripts120  scripts150

Btw, rebuilding nvblox_ros (including the package nvblox_rviz_plugin) from source didn't help. Maybe nvblox_rviz_plugin needs some changes to fit the abandon of GLSL 150.

Hi there. Thank you for pointing this out.

This originated in a change to ROS, which was backported to humble, and rolled into our Isaac ROS base images. The change removed the shader files we rely on. We're in the process of push a fix, which will ship the shader files as part of isaac_ros_nvblox.

In the meantime one can run a back-up shader by setting:

export ISAAC_ROS_NVBLOX_PLUGIN_FORCE_FALLBACK_MATERIAL=1

The voxels are just visualized as points instead of cubiods. Anyway, a fix should arrive soon.
