Negative Density Values on Water

Not sure if this is a bug or just...I dont even...xD...just watch =P



Like I said, I set the density of the water to about -500 or -700 or something, and this happens lol. As show in the beginning, the cars just bug out and it comes up with some error and i have to reset. Other times though (at the end of the video) it doesnt bug out and the cars just get literally torn apart xD kinda cool. Maybe this is a good way to test the physics? Since it obviously causes that error almost 80% of the time. (happens 100% with the van and some other vehicles that seem more unstable with the physics).

edit:

did another quick video cause i thought this was interesting to watch in slomo how the water rips the van apart

 

To create a density below 0, either the mass or the volume must me smaller than 0. That's physically impossible. If a physicsengine, which works with realistic calculations, crashes when a situation that can't exist is created, i call it a feature not a bug
