Just modify 2 lines from the scripts and you get visible waterplane when going below surface. The idea is to check camera Y position, if below 0, flip normal and flip matrix for mesh. Boat Attack Project:https://github.com/Unity-Technologies/BoatAttack Inside Water.cs & PlanarReflections.cs replace these 2 lines:

(screenshot with Quad mesh placed on top of Plane with raycast hit.point) If you want to use Raycast hit.point to place quad on a flat surface, it will most likely create Z fighting issue.. You could add position offset by hit.point+Vector3(0,0.1f,0), Or use modified shader […]

These snapping features are super useful! Note that if you have “Pivot” enabled instead of “Center”, it snaps from the center of the sphere instead. Surface Snapping While dragging in the center using the Translate Tool, you can hold Shift and Control (Command on Mac) […]

One more water shader test.. Its almost default specular shader with normal map(s) and “bottom texture”.. Webplayer: http://unitycoder.com/upload/demos/SeaSurface3/ Download source: coming later..

Sea Waves testing. Its quite “heavy”..but looks nice. Info v1.0: – Special perlin noise map (128×128) is updated every frame and used as a height/waves-map for the sea mesh (converted from “Heightmap Test” by Simon Bethke, licensed under Creative Commons Attribution-Share Alike 3.0 and GNU […]
