Hi,

I want to make a ground fog (with a small heigth) which flows through a forest towards the cam. Later when the fog on the ground has reached it it should rise up and cover the whole forest with fog.

The problem with the fluids is that i can't hold them down on the ground. The collissions of the ground and the trees push the fog up too much.

I also tried to make the fog with a surface flow and particles but there i wasn't able to create collissions with the trees.
Moreover i can't make a good looking collision with normal particles because i don't know how i could let the particles collide like fog on the trees. They have to flow around it. Any idea?

You could download the fluid scene here to see what i mean.

Thanks for help.
