Hello there,

Im trying to import some model from 3dwarehouse, and I have created a .world file following this. But now,I realized if I want to insert this model to other world, I must convert it to a .sdf file which I have failed so many times. Can anyone help me? This is my .world file:

<?xml version="1.0"?>
<sdf version="1.4">
  <world name="default">
    <model name="clock">
      <pose>0 0 0.49  0 1.57079 0</pose>
      <link name="up">
        <visual name="visual">

And I have created the model.sdf, model.config and other files, but it still doesnt work.

├── materials
│   ├── scripts
│   │   └── clock.materials
│   └── textures
│       └── material_22.png
├── meshes
│   └── model.dae
├── model.config
└── model.sdf

The .sdf file:

<?xml version='1.0'?>
<sdf version='1.6'>
  <model name='clock'>
    <link name='up'>
      <pose frame=''>0 0 0 0 -0 0</pose>
      <visual name='visual'>
          <shader type='pixel'/>
        <pose frame=''>0 0 0 0 -0 0</pose>

The scripts:

material clock
        texture material_22.png
    scale 1 1

Fix the mesh uri. <uri>model://clock/meshes/model.dae</uri>

The bit you're missing is probably setting the GAZEBO_MODEL_PATH environment variable. Do it like this:

export GAZEBO_MODEL_PATH=<path to parent directory of clock>:$GAZEBO_MODEL_PATH

Also make sure that your model's directory is called clock.

What Gazebo does is substitute model:// with <path to parent directory of clock>. So it will load:

<mesh><uri><path to parent directory of clock>/clock/model.dae</uri></mesh>

I have put the files in the ~/.gazebo/models/ directory, and I can find the model's name in the side navigation bar but cant add the model to world.
