WATER MESH RESOLUTION

On the coastline level, where water surface is heavily distorted by waves, occasionally, we see the polygons of the water geometry. Water meshing is managed by the SurfaceAlignedMeshesutility. LOD is applied. On the closest-to-camera water tile the utility uses 500x500 polygon mesh - covering the 100x100 meters simulated area - which means: we have 5x5 polygons per meter ---- this could be improved by replacing the mesh, on the Actor Details Panel / User Parameters of Surface Aligned Meshes.

Alternatively, the blocky visuals are not the result of the low-polygon density of water-mesh, BUT the low resolution of the Pressure Buffer.
Pressure Buffer resolution could be improved using this param:
SET /LiveComponent /LiveOutputRenderTargets /SimPressureDivergence /BufferDownScaleFactor from 2 to 1
