<span style="color: #000000">This nodes allows artists to place patterns using a 2D solution that typically relies on UVs provided by the artist. You may transform the resulting placement (translate, rotate, etc) or repeat the pattern using the controls below</span>. This node also provides the correct useful derivatives needed for bump mapping.

### Input Parameters

#### Center

Transformations are centered here

#### Angle

Rotation angle around origin.

#### Scale S

Frequency of a feature in the S direction.

#### Scale T

Frequency of a feature in the T direction.

#### Offset S

Offset from the origin in the S direction.

#### Offset T

Offset from the origin in the T direction.

#### Invert T

Flip the manifold in the T direction.

#### PrimVar S/ST

Name of custom 1D S or 2D ST primvar.

#### PrimVar T

Name of custom 1D T primvar.

#### uvSet

Default is ST


### Output Parameters

#### result

The 2D manifold.

#### resultS

A float representation of the S component of the manifold.

#### resultT

A float representation of the T component of the manifold.
