Hmm, i think i just fixed wave reverse speed and smoothed the moment when wave stops moving forward and begins to move backwards. A bit late here and im too tired to record video right now. Still need to update opacity, normals and especially foam to match the new wave movement (atm foam just controlled by the depth mask and i dont like the result).
p.s. - and im really need to do something about video quality, it seems ok before i upload it to youtube. Any advice?
