Controlling player movement in smooth terrain water?

Hi all,

I’m interested in adjusting the movement of players when they are in smooth terrain water. Specifically, I’d like to adjust how a player floats to the surface when submerged. I couldn’t find the code for that in the control modules. Does anyone know if that is accessible and where it might be? Currently, I’m just trying to sort out if that “float to surface” movement is a physics thing or an extra translation added to controller code for swim state or what. I know how to change the animations.

Thanks for your thoughts.
