$\space$ OS: Linux Ubuntu 22.04
$\space$ gazebo version: garden
$\space$ I downloaded the sdf from here, it is supposed to look like this enter image description here $\space$ but in my simulation it looks like this enter image description here I think it's caused by some errors when loading the matetial, in model.sdf the material element looks like this.


I read the Material.cc in sdfformat/src and I found that the script seems to have been implemented here.

if (_sdf->HasElement("script"))
    sdf::ElementPtr elem = _sdf->GetElement("script", errors);
    std::pair<std::string, bool> uriPair =
        elem->Get<std::string>(errors, "uri", "");
    if (uriPair.first == "__default__")
      uriPair.first = "";

    if (!uriPair.second || uriPair.first.empty())
          "A <script> element is missing a child <uri> element, or the "
          "<uri> element is empty."});

    this->dataPtr->scriptUri = resolveURI(uriPair.first, _config, errors);

    std::pair<std::string, bool> namePair =
        elem->Get<std::string>(errors, "name", "");
    if (namePair.first == "__default__")
      namePair.first = "";

    if (!namePair.second || namePair.first.empty())
          "A <script> element is missing a child <name> element, or the "
          "<name> element is empty."});
    this->dataPtr->scriptName = namePair.first;

so maybe there's something wrong in rendering? I wonder.

Gazebo Sim does not support the material script, this is mentioned in the migration guide.

The proposed alternatives are to either use plain colours, or to use textures.

  • $\begingroup$ I tried the pbr in material. But pbr do not have a scale element in sdf, is there any method to save this. $\endgroup$ Commented Oct 6, 2023 at 7:33
  • $\begingroup$ What I would do is to redraw that model in Blender, apply the texture, export as DAE and load the DAE as mesh in the SDF. $\endgroup$
