[ros-users] Material-dependent transparency in Gazebo

Apologies if this issue has been addressed previously, but I was unable to
find an answer in the list archive or simulator_gazebo pages.

My problem is that whenever I spawn a gazebo object with certain basic
material properties (e.g. Blue, Gold), it is transparent when viewed in
front of the ground plane. If I adjust the camera to look at it
horizontally, I can then see the top part of the object that projected onto
the sky.

However, if I spawn the same object, but change its material to, e.g.
RustySteel, it is completely visible. For example, if I spawn the table
object using the table.launch script in gazebo_worlds, I can see the table
top (LightWood) but not the legs (Red). There are no error messages in the

Does anyone know how to fix this problem? I'm sure there's a relatively
straightforward solution, but it has alluded me so far :)

System info:
Ubuntu Maverick (2.6.35-25) 64bit running on Parallels VM on MBP i7
ROS C Turtle, all packages are up to date.

I was also able to reproduce this problem on a Dell Quad Core running 64bit

Thanks in advance!
