# 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.
