Vector3 Node

The Vector3 node ( shortcut: numeric 3 key ) generates a float3 value containing three float components. This value is usually useful to either define a Constant value which is directly used in shader calculations or to define an exposed Property value that can be modified by the material inspector that uses it. Note: Unity's material inspector for vector3 properties display as vector4 containing four values instead of three, this means the last value is ignored and does nothing.

Nodes used: Vector3

Node Parameter	Description	Default Value
Type	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: 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.	Constant
Name	Name of the property holding the value. This is the name that will be shown in the material properties label if type is set to Property, if not this name is ignored but still useful for organization purposes or to generate a Property Name	Vector #
Variable Mode	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	Create
Auto-Register	If toggled on, creates the property and/or global variable even if not connected to an Output node	Off
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	Float
Default Value	This is the value the shader currently holds. It's also the default value that is used when a new material is created with this shader.	0
Other Parameters
Property Name	This is the variable name that contains the value, this is automatically generated using the 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 Property, Instanced Property and Global types to indicate what's the variable name to use when editing this value by script.	_Vector#
Material Value	This is the value the node the material currently holds. This parameter is only visible in Property and Instanced Property types which are the two types that let you change the value per material.	0
Attributes
Hide in Inspector	Does not show the property value in the material inspector	Off
HDR	Indicates that a property expects a high-dynamic range (HDR) value	Off
Gamma	Indicates that a property is specified as sRGB value in the UI and possibly needs conversion according to color space used	Off
Per Renderer Data	Indicates that a property will be coming from per-renderer data in the form of a MaterialPropertyBlock.	Off
Header	Sets up a title for that property, to be automatically shown over the material inspector.	Off
Custom Attributes	Allows adding custom attributes directly on a textfield	-

Output Port	Description	Type
XYZ	Returns the assigned vector3 value	Float3
X	Returns only the X component of the vector3	Float
Y	Returns only the Y component of the vector3	Float
Z	Returns only the Z component of the vector3	Float
