Grid Fluid and Wetmap

[BrianLooney]

Grid fluids aren't creating wetmaps very well based on resolution. I think the particles don't get close enough to the object to create the map, only if high velocity is creating a collision with the object. So if there is just a pool of particles on a surface, the wetmap remains all black because the particles are held away from the object.

On second look, the grid particles may not be influencing the wetmap at all. I think only the splash particles have an influence.
