====== Material Profile ======

Scriptable Object that contains configuration for material used to render Water Surface.
\\
\\ **NOTE:** If you are changing mateiral profile values via scripting, you will have to mark surface material by calling ''SetMaterialDirty'' or ''SetMaterialsDirty'' on material profile object.

===== Base Material Settings =====

{{:water:material_profile_base.png?direct&400}}

Here you set basic material settings. They can be affected by modiffiers in sections below.


----
===== Color Noise =====

{{:water:material_profile_noise.png?direct&400|}}

Additional color noise.

==== Hillness ====
Lighten/Darken base color depending on hillness value.
\\ It's kind of addional layer to simulate water depth and SSS that comes from it.

==== Texture ====
Global color modiffication that comes from two animated textures that are blended using **min** operator.
\\ Both textures must be grayscale R-channel textures.


----
===== Subsurface Scattering =====

{{:water:material_profile_sss.png?direct&400|}}

  * **Overlay Strength** - how much final SSS will affect output base color.
  * **Emission Strength** - how much final SSS will affect output emission.


----
===== Normal =====

{{:water:material_profile_normal.png?direct&400|}}

By default, the only normal source is the one that comes from waves.
If enabled, you can set up two normal maps, that will be animated and blended toether.
  * **Normal Global Strength** - global normal strength that also affects waves normal.


----
===== Foam =====

{{:water:material_profile_foam.png?direct&400|}}

If enabled, foam will be rendered.
\\ Main texture and color settings are shared between edge foam and 1st layer of hillness foam.
\\ All textures here must be grayscale R-channel textures.

  * **Normal Attenuation** - how much water normals will be attenuated by foam.
    * **Bias** - higher value means more foam will be required to attenuate normals.

==== Edge Foam ====
Foam that is rendered on edges, where water meets land and other objects.

==== Hillness Foam ====
Kind of global foam whose intensity depends on hillness - usually, with higher hillness value you want more foam.
\\ Read more about hillness value: [[.wave-profile#hillness]]

==== Extra Hillness Layers ====
When enabled, you will can configure extra 2 layers of hillness foam, each with own noise texture and color.
\\ Result of all layers is weight-blended for final output.


----
===== Transparency =====

{{:water:material_profile_transparency.png?direct&400|}}

  * **Opaque** - no transparency, simplest option.
  * **Transparent** - surface is transparent and transparency comes from output colors' alpha.
  * **Refraction** - requires Opaque Texture enabled in renderer. Transparency comes from output colors' alpha.
    * **Distance Factor** - determines distance, where strength becomes 100x lower. Can depends on camera FoV - set it so refraction looks same from both, near and far distance. Default value of 100 is a good starting point.


----
===== Reflections =====

{{:water:material_profile_reflections.png?direct&400|}}

  * **Off** - no reflections. Same as Simple with black color.
  * **Simple** - simple reflections where you set a single color.
  * **Default Environmental** - default enivornmental reflections, that you configure in Unity's Rendering window. This mode also supports blended reflections from Reflection Probes.
  * **Cubemap** - similar to default environmental reflection, but overrides cubemap with custom texture. Does not support blending.

**TIP**: If reflections intensity slider does not work on fresh scene, make sure your scene have configured and actually saved settings related to reflections in Rendering > Lighting > Enivironment window.


----
===== Ripple =====

Modiffiers for settings above, used only when ripple is enabled for surface using this profile.
