Mesh file not loading in RVIZ and Gazebo

Hello ros developers. I'm new in ROS and I'm trying to create a robot using this .xacro file:

<?xml version='1.0'?>
<robot name="teste_bot" xmlns:xacro="">

  <!-- Import Rviz colors -->
  <xacro:include filename="$(find ntu_gazebo)/urdf/materials.xacro" />

  <!-- Base Link -->
  <link name="base_link">
      <origin xyz="0 0 0" rpy="0 0 0" />
          <mesh filename="file:///home/gilmar/ros_ws/simulators/src/ntu_gazebo/meshes/chassis.stl" />
      <material name="black"/>

and this launch file:

<?xml version="1.0" encoding="UTF-8" ?>
    <!-- Valores passados por linha de comando -->
    <arg name="model" />
    <arg name="gui" default="False" />

    <!-- seta os parâmetros no Servidor de Parâmetros -->
    <param name="robot_description" command="$(find xacro)/xacro '$(find ntu_gazebo)/urdf/$(arg model)'" /> <!--textfile="$(find ntu_gazebo)/urdf/$(arg model)"/>-->
    <param name="use_gui" value="$(arg gui)"/>

    <!-- Inicia 3 nós ros -->
    <node name="joint_state_publisher_gui" pkg="joint_state_publisher_gui" type="joint_state_publisher_gui"/>

    <node name="robot_state_publisher" pkg="robot_state_publisher" type="robot_state_publisher"/>

    <node name="rviz" pkg="rviz" type="rviz" args="-d $(find ntu_gazebo)/urdf.rviz" required="true"/>

but I'm having a problem loading the mesh. All the files are in the respective directory so that when I launch the node no error seems to occur, but the mesh simply doesn't show up. Does someone know what is happening?

I've solved the problem. The main effect was caused by the OpenGL version. I have created a virtual machine in WSL, and it does not have OpenGL 4 support.

I have the same problem, maybe also caused by my virtual machine in WSL. How did you resolve it?

I needed to update my OpenGL version in WSL 2. Here is the link that I have followed.

"file:///home/gilmar..... , after file you use three///, try two //, and package, try bottom

<mesh filename="package://home/gilmar/ros_ws/simulators/src/ntu_gazebo/meshes/chassis.stl"/>

Do you spawned your robot on Gazebo? In launch file, this not exist. spawn:

<node name="urdf_spawner" pkg="gazebo_ros" type="spawn_model" respawn="false" output="screen"
args="-urdf -model deneme_1 -param robot_description"/>

deneme_1 your robot name: teste_bot
