Hello, I've have been working with underwater robotics simulation on Gazebo and one of the challenges is how to make the world more realistic. To simulate the water turbidity I tried using the fog from Gazebo, but I would like to have it only underwater. Is it possible to set the region where the fog should be generated?

Currently we don't support setting the fog bounding box. Fog is normally a visual effect applied to the camera viewport and not tied to a 3D space in the world. You would need to look into writing your own shaders and setting them as the visual material for the underwater model to achieve the desired effect.

I thought so. We have been applying the shaders to generate waves on the water surface and it works fine. I will look into shaders for fog and floating particles. Thanks for the information!
