I made a plane, and subdivided it fractally a couple of times and made it a particle emitor.
For particle setting, I left everthing default except the life and end and put a force of -1.0 in the z axis.
This should make the particles fall down, right?
Well, instead, the particles go up above the plane, and then fall down.
Why? It works properly on a regularly subdivided plane, why not on a fractal one? I have 0.0 for the normal speed.
