Mesh display error

[InguChoi]

I installed the mesh_tools, the uos_tools-master, the mobe_base_flex, and the pluto_robot.
I have two problems.

1. roslaunch pluto_gazebo pluto_botanical_garden.launch
   -> I can not see the meshed map. I just can see the gray-scale map

2. roslaunch pluto_navigation botanical_garden_osnabrueck.launch
   -> The error message is "Mesh display: no visual available".

I encountered the same problem, even though I had already installed git lfs and completed the configuration and pulling according to the steps in readme
