Smear is a utility node that allows you to convert an RGB color into a UV coordinate offset.

This allows you to "smear" UV coordinates using a texture to define how the coordinates are remapped. To better understand how this works, the color is converted internally to the HSV "color wheel" representation, and the angle on the wheel and distance from its center are treated as polar coordinates in the UV space, which are then converted to rectangular coordinates and ouput as the resulting UV offset.

In the table below, important attributes have their names listed in bold in the description column.

Long name (short name)	Type	Default	Flags
inRgb (i)	float3	0.0, 0.0, 0.0
Input Color is the RGB value which determines how far and in what direction to offset in UV.
inColorR (ir) float 0.0 The red component of Input Color.
inColorG (ig) float 0.0 The green component of Input Color.
inColorB (ib) float 0.0 The blue component of Input Color.
outUV (o)	float2	0.0, 0.0
Out UV: This attribute should be connected to the UV Coord attribute of the 2d texture being placed.
outU (ou) float 0.0 The U component of OutUV
outV (ov) float 0.0 The V component of OutUV
