Hello, I was making unit 2 of TF ROS2, I put the correct settings in rviz to be able to finish the unit successfully but the visual part of the model is not shown, only the collision part. The URDFs are “ok” so it doesn’t seem to be an error on that side.

And this is the shell:

where is the turtle\_tf\_3d\_ros pkg?

Hello @Voltedge,

Have you tried this?:

> [@Unit 2 - Example 2.6.1 - Turtle and cam\_bot are not shown in RVIZ2](https://get-help.robotigniteacademy.com/t/unit-2-example-2-6-1-turtle-and-cam-bot-are-not-shown-in-rviz2/21866/4):

> Hello Jose Enrique, apparently Rviz can’t find the meshes. Try this: first source the workspace where the robot models are located: Execute in Terminal 2: source /home/simulations/ros2\_sims\_ws/install/setup.bash Then start Rviz in Terminal 2 rviz2 Hope this helps, Roberto

See if that solves your issue and don’t hesitate to write a follow-up post if it doesn’t.

Cheers,

Roberto
