Water material type

Texture Units

Diffuse: base color for the material.
NMap: Normal Map, per-texel surface normal data. When enabled, the surface will get shaded according to the normal info.
CubeMap: this unit will make the material look as if reflecting an environment given by a cubemap texture.

RefractionScale: The amount reflection and refraction is offset by ripples in water.
FrenselBias: Bias for Fresnel term. values: 0-1. Higher means that more of reflection is seen when looking straight at water.
FrenselPow: The higher the 'sharper' the reflection is, meaning that it is only clearly seen at sharp angles.
WaveSpeed: The speed of the waves.
WaveAmplitude: The size of the waves.
WaveFreq: The frequency of the waves.
ReflectionFadeStart: Where the reflection starts fading.
ReflectionFadeEnd: Where the reflection stops fading. 0 or less means no fading.
HasReflection: If a reflection should be shown or not.
OcclusionCullWorldReflection: If occlusion culling should be used on reflection.
LargeSurface: If the water will cover a large surface and will need special sorting when rendering other transperant objects.
HasVertexWaves: If the vertices are animated.
VertexWaveSpeed: The speed of the vertex waves.
VertexWaveAmplitude: The size of the vertex waves.
VertexWaveFreq: The frequency of the vertex waves.
FadeWhenShallowMul: This determines when the water should start fading when in shallow water. In meters.
FadeWhenShallowPow: fast the shallow water drops off, higher means faster, lower means slower.
