how do I make mud? I used a fluid container and filled it half way with fluid. I made a ball that moves to collide with it. It works, but no matter what I try, the fluid ssems to constantly want to creep upwards to fill the box. ive adjusted density, gravity, etc etc and nothing seems to work. I just want to be able to 'throw' the ball into the fluid and make it affect it as if it were mud. Also, when the ball interects with it it doesnt 'move' the fluid, it just seems to cut out a perfect hole in the shape of the ball. Any help would be nice, thanks in advance.
