Problem adding collada file

Hi all, My name is Arturo, this is my first post. I am trying to modify the turtlebot adding it a tag with texture made with Blender and exported as Collada file. I add the tag to the model like this: 0 0 0.44 0 0 00.4 0.2 0.010 0 0.44 0 0 0truemodel://turtlebotJde2cam/meshes/tagtext1.dae0 1 0 1 And when I try to run my world where this model is added, I is stacked here and nothing happens: [Msg] Waiting for model database update to complete... [Wrn] [Publisher.cc:141] Queue limit reached for topic /gazebo/default/pose/local/info, deleting message. This warning is printed only once. Any clue to fix this problem? The model has more .dae files which are in the same folder than the one i was created with blender. Thanks in advance, cheers, Arturo.
