Hallo Gazebo-Users,

I try to change the color of a Link of a robot. The robot is written in URDF/Xacro. The Link is a Link without a mesh.

In Gazebo 2 it worked using the gazebo-element:

<gazebo reference="link-1">
 <material>Gazebo/FlatBlack</material>
</gazebo>

Now I updated to Gazebo5 and the Link is white.

How can I change the color of the link?

Have you managed to solve this problem? I am encountering it as well. Not just with custom URDFs but the standard world files provided with gazebo

I think you might be experiencing this issue.

As described in the link above, you need to remove the name atribute from the visual tag of your link definition.

Take a look to these links :

http://answers.gazebosim.org/question/3336/change-color-of-models/

http://sdformat.org/spec?elem=material

You can change the color with the ambient, diffuse, etc ... tag.

<gazebo reference="your_link_name">
  <visual name="blabla">
    <material>
      <ambient>1 0 0 1</ambient>
      <diffuse>1 0 0 1</diffuse>
      <specular>0.1 0.1 0.1 1</specular>
      <emissive>0 0 0 0</emissive>
    </material>
  </visual>
</gazebo>

Hello @Brosseau.F, I tried the way you explained but it doesn't work. This works with SDF but the model is in URDF.

Do you have a "/usr/share/gazebo-5/media/materials/scripts/gazebo.material" file? Do you have an error/warning message ?
