This is probably more a Gazebo question (and thus more suited for answers.gazebosim.org), but let's see whether someone here has a suggestion.

Yes i know. I asked the same question in Gazebosim forum. but maybe someone has any idea here.

Hm. cross-posting is not really nice.

Could you at least post the link to your GazeboSim Answers question?

you can use "Block Laser" plugin, but last time I used it it was pretty resource hungry. http://lmgtfy.com/?q=3d+lidar+gazebo

You can consider velodyne's implementation which extends the default gazebo_ros_block_laser to publish PointCloud2

Just run

sudo apt install ros-melodic-velodyne-gazebo-plugins

and replace, in your model.sdf, libgazebo_ros_block_laser.so with libgazebo_ros_velodyne_laser.so
