How to view URDF files in RViz or Gazebo?

[dhruvsasuke]

I have been trying to visualise the URDF files using RViz and Gazebo, but it seems that the meshes are incompatible with RViz and Gazebo. The URDF was parsed correctly since the transformation axes were visible in RViz but, the meshes were unable to load. Similarly in Gazebo, the model was successfully imported (shown in the left pane under models) but nothing was visible.

Above image shows the errors in loading the RobotModel

As we can see, the TF has been loaded correctly
