[Ignition Edifice] ERROR: Non-unique names detected in XML children of model...

Hi everyone,

I have this problem when I run the demo worlds available for Ignition Edifice:

Warning [Model.cc:170] Non-unique names detected in XML children of model with name[demo_name]

For example, in the case of the "multicopter_velocity_control.sdf", in addtiion to the previous message, gazebo shows a strange thing in the world (see image below).

It happens for different world samples in Ignition Edifice.

Could you help with these issues? Please.

The mesh problem that is causing this mess on screen is a known issue with locales.

Setting this environment variable will solve it:

export LC_NUMERIC="C"

The "Warning [Model.cc:170] Non-unique names detected in XML children of model with name[demo_name]" is related to a link/joint/tag in the SDF model with same name that other link/joint/tag. It is not exactly a problem and the simulation will work fine. You could open the SDF model and try to search which one have the same name and change it, or just ignore this warning.
