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 or Triplanar node.
