Here's all the MAIN settings, I think. What I did was just tweak the White Water part of Chris's water mat. The switch I made was using the "Complex Cracks" as both for COLOR production as well as TRANSPARENCY production.

The "Influence on Environment" was the other factor that causes the "sudsy water" to appear near the top of the waves.

BTW- Bryce users may recognize the "Complex Cracks" water effect. It was one of my favorite waters when using Bryce.
I've found that, over time, I can create nearly ALL of the Bryce material effects in Vue-- you just have to play around with the Advanced Material settings, filters, functions, etc.
