Notes:

To make "FX_OceanWater" shader compile, edit the shader:

1. In "WaterSim" node doubleclick "FX_OceanWater_Timestep", find "Custom Hlsl", in Details change "Absolute Include File Path" (3 dots) to your "OceanComplexMath.ush" file path,
2. Repeat: in "FX_OceanWater_Rowpass" -> "OceanWater.ush",
3. Repeat: in "FX_OceanWater_Colpass" -> "OceanWater.ush",
4. Repeat: in "FX_OceanWater_ExportData" -> "OceanExport.ush",

If you're getting glitched ocean, find "OceanWater.ush" file and search for "groupshared float3 pingPongArray" there, change "[256]" to something like "[128]" or "[64]".
