realistic water sinking Physics with world editor

Just recently i found a way to make cars slowly sink in water as they lose air in the cabin, instead of immediately sinking to the bottom. all you wanna to do is open world editor, click on the body of water you want to edit and set both the density values to (10300.000) and the viscosity values to (10300.000) as well. i know this is probably already known about but its still pretty cool. (video down below)

 

yeah ive used this for a while, thanks!
