Changes compared to old (Ogre) water: - Uses depth-texture readback to handle the underwater fog in the water shader, instead of handling it in the object shader - Different clipping mechanism (glClipPlane instead of a skewed viewing frustum) - Fixed bug where the reflection camera would look strange when the viewer was very close to the water surface - Toned down light scattering, made the waterColor a bit darker at night - Fixed flipped water normals and strange resulting logic in the shader Still to do: see comments...
