problem with mesh orientation in rviz [closed]

edit

Hello everyone. I want to display a marker in rviz with the shape of a person. I found a .dae model on the web. I send the marker information trough the proper topic and I am able to visualize the mesh model in rviz. The problem is that, when I use some keyboard command to make the model rotate, it does not. It is strange because I am displaying other robots as "marker" and they receive the orientation (obviously the code I am using is the same). I've never created a .dae model and looking into the file I cannot figure out what is wrong =( Any expert? Otherwise, can someone tell me where I can find mesh models of a "person" (even a humanoid robot is ok) that can work in rviz?

Thank you.
