OMG, that's soooo Cool... I see that the dust and debris changed their direction, how did you manage that?
Oh, one thing I noticed is that the fog move trough the ground, maybe you can avoid this by fade it out when the height is very low.
I was thinking about that too, but that would EAT framerate...
Maybe i can borrow some Shade-c another day and make them soft particles.. But i dont know how that would impact the framerate
will try that some other time
