Custom UV node — Material Maker documentation

# Custom UV node

The Custom UV node is variadic and deforms one or more input images according to a custom UV map given as input.

## Inputs

The Custom UV node accepts two inputs:

- The Source inputs is the image to be deformed.

- The UV input is a color image whose red and green channels are used as U and V (X and Y in texture space) coordinates, and the blue channel holds a value to be used for pseudo-random scale and rotate transforms.

## Outputs

The Custom UV node outputs the deformed image.

## Parameters

The Custom UV node accepts the following parameters:

- Inputs is the number of alternate shapes in the input (1, 4 or 16). Images containing several shapes can easily be created using the Tile2x2 node.

- Scale X and Scale Y are the scale along X and Y axes applied to each instance.

- Rnd Rotate is the maximum angle of the random rotation applied to each instance.

- Rnd Scale is the amount of random scaling applied to each instance.

- UV Mode defines the behavior beyond the limits for the input UV:

  > - Clamp stretches the edges

  > - Repeat tiles the input UV

  > - Extend shows parts of the input UV that are beyond the edges

- Variations: if checked, the node will deform different variations of its input (i.e. roll a different seed for each instance)
