Hi, I just watching the waterfall tutorial(by SideFX) and try to make one.
everything is fine exclude the spray. my spray even did not collide with surface, it will floats on air !?

thank you a lot !

I think you will find that the spray does weird things outside the bounds of the sim because the surface sdf data and velocities only exists inside the simulation grid. The data that is used for the velocities and surface position outside the grid are usually just the last voxel smeared in the direction out from the sim (You can see as the foam on the right lifts up to the positing of the surface on the edge of the grid).
You would be best to delete the particles outside the sim bounds.
