Height values & bouyancy forces

[Reitmania]

Hi, nice video on yt and nice shader! Would it be possible to extract the height values of the water surface to implement bouyancy forces depending on the ripples? Did something similar in Unity, but I stuck at reading height values from the simulation colorrect (if this is even correct).

Did you use get_pixel at mouse pos for the simulation texture.
