When i try to use the gpu ray sensor in my velodyne model urdf file, it is not publishing any topic. When i put the same line of code for sensor in another urdf file of another robot it works fine and i can also visualize the topic in rviz, but i cant use the same sensor in below urdf file, what is the problem can anyone once check it. Here when i launch it in gazebo i can clearly see the blue laser coming out from the model. 0 0 0.025 1.5707 0 0 true 30 30 0.01 -0.174 0.173 0.001 100 0.01 gaussian 0.0 0.01 /velodyne/laser/scan camera_link
