Chaos vantage pool animation

[PTMV]

Hello friends, I'm doing an animation project of a waterfall falling into a swimming pool, I managed to export the animation to Vantage by converting the scene to Vray, the only thing I couldn't do was make the foam and splash effect appear, I can only make the water, is there anything I need to do to make this happen? I wanted the effect like something done in this video
