| == Color Node ==
| |
|
| |
|
| The Color node ''( shortcut: numeric 5 key )'' generates a float4 value containing four float components. This value is usually useful to either define a [[#paramtype|Constant]] value which is directly used in shader calculations or to define an exposed [[#paramtype|Property]] value that can be modified by the material inspector that uses it. The function of this node is very similar to the [[Unity Products:Amplify Shader Editor/Vector4|Vector4 Node]], the difference is the convenience of representing and changing the values with a color picker.
| | == Fog And Ambient Color Node == |
|
| |
|
| <img class="responsive-img" src="http://wiki.amplify.pt/images/NodeDetail/ColorNode.jpg"><br/> | | The Fog And Ambient Color node outputs specific data regarding both fog and ambient light. The required data is selected via the [[#paramColor|Color]] option. |

| |
| | A set of ways the value behaves in different situations.
| |
| * '''Constant:''' the value is assigned directly in shader code and can't be dynamically changed.
| |
| * '''Property:''' the value becomes available in the properties of the material that uses the shader and can be changed in the material inspector or by script.
| |
| * '''Instanced Property:''' the value can only be set by script and this defines the shader as an instanced shader. ( see more here: [https://docs.unity3d.com/Manual/GPUInstancing.html GPU Instancing] )
| |
| * '''Global:''' the value can only be set by script and this defines a static variable that is shared between all shaders that use it. It's useful to change a value globally.

| | Defines if the current property/global variable is to be created on the current shader.
| |
| * '''Create:''' Property and/or global variable is created in the shader
| |
| * '''Fetch:''' No variable nor property is registered on shader, useful when p.e. there's need to using global variables declared over a included cginc

| | id="paramprecision" | Precision
| |
| | Defines the amount of bytes the variable can hold, effectively defining how precise the value is. It's usefulness is bond by the hardware specifications necessary. Lowest precision is slightly faster but might produce errors and artifacts.
| |
| * '''Float:''' Highest precision, useful for values that can be very high or very low in value (ie: positions, coordinates, etc)
| |
| * '''Half:''' Medium precision, in most cases is as good as '''Float''' but at half of it's precision
| |
| * '''Inherit:''' Use global precision set on master node properties

| |
| | This is the variable name that contains the value, this is automatically generated using the [[#paramname|Name]] parameter, it's greyed out and not editable. The generation process removes special characters, whitespaces and adds an underscore at the beginning ( ie: "''My Property Name''" becomes "''_MyPropertyName''" ). This parameter is only visible in [[#paramtype|Property]], [[#paramtype|Instanced Property]] and [[#paramtype|Global]] types to indicate what's the variable name to use when editing this value by script.
