Make water non detectable by lidar

[mvanlobensels]

In real life, lidar is absorbed by water instead of reflected. Do you know how to make the water non detectable by lidar in Gazebo? Essentially removing the ground plane in a way.

Do you have an idea how collision between lidar rays and the water can be detected for filtering?

Could try adding a <laser_retro> element with a low value to the waves visual.
