Strange effect when importing DAE model retrieved on the web

edit

Hi all,

I'm trying to enlarge my models database by retrieving models from the 3D warehouse.

As a reference I'm following this tutorial. And the procedure I follow to generate a COLLADA model is the following.

To check the outcome of the procedure, I open the .dae model with Meshlab. And this is what I get!

So, I'm pretty happy with the result!!!

Next, I create a gazebo model in the following steps:

• go to ~/gazebo/models folder
• create a folder to store the necessary files (e.g. ./armchair)
• create model.config and model.sdf files
• copy the model.dae file in the ./armchair/meshes folder
• copy the texture images (if any) in the ./armchair/materials/textures/ folder

where the model.config file contains:

<?xml version="1.0"?>

<model>
  <name>armchair</name>
  <version>1.0</version>
  <sdf version="1.5">model.sdf</sdf>

  <description>
  Armchair
  </description>
</model>

and the model.sdf:

<?xml version="1.0" ?>
<sdf version="1.5">
  <model name="armchair">
    <link name="link">
      <pose>0 0 0 0 0 0</pose>
      <collision name="collision">
        <geometry>
          <mesh>
            <uri>model://armchair/meshes/model.dae</uri>
          </mesh>
        </geometry>
      </collision>
      <visual name="visual">
        <geometry>
          <mesh>
            <uri>model://armchair/meshes/model.dae</uri>
          </mesh>
        </geometry>
      </visual>
    </link>
  </model>
</sdf>

When I insert the model in gazebo, this is the picture:

As you can see the textures are correctly loaded, but the edges of the model are marked in white!

Can someone please explain me what's happening?

Thanks.
