Community Tutorial: Ocean Simulation

I also noticed that the downloadable project has more modules. Are FX_OceanWater_Tick4WaveGroups, FX_WrapGroupIndex, FX_OceanWater_CrossFadeWaveGroups, FX_OceanWater_PopulateWaveGroups used anywhere?

Also foam parallax is calculated differently in the tutorial and project:


Which one is correct?

Finally, I think the tutorial didn’t mention how to set all those parameters on the object itself. The default values will work but won’t look as good.
