# Normal Unpack Node
## Description
Unpacks a normal map defined by input **In**. This node is used to unpack a texture that is defined as a **Normal Map** in its Texture Import Settings when it is sampled as if it were a default texture.
Note that in most cases this node is unnecessary as the normal map should be sampled as such by setting its **Type** parameter to **Normal** when it is sampled using a [Sample Texture 2D](Sample-Texture-2D-Node) or [Triplanar](Triplanar-Node) node.
## Ports
| Name | Direction | Type | Binding | Description |
|:------------ |:-------------|:-----|:---|:---|
| In | Input | Vector 4 | None | Input value |
| Out | Output | Vector 3 | None | Output value |
## Controls
| Name | Type | Options | Description |
|:------------ |:-------------|:-----|:---|
| Space | Dropdown | Tangent, Object | Sets the coordinate space of the input normal. |
## Generated Code Example
The following example code represents one possible outcome of this node per **Space** mode.
**Tangent**
```
void Unity_NormalUnpack_float(float4 In, out float3 Out)
{
Out = UnpackNormalmapRGorAG(In);
}
```
**Object**
```
void Unity_NormalUnpackRGB_float(float4 In, out float3 Out)
{
Out = UnpackNormalmapRGB(In);
}
```
