# Select node

The Select node assigns one or more 3D textures based on samples whose color index match the color parameter.

## Inputs

The Select node accepts two or more 3D texture inputs:

- The default texture, used for all samples that don’t match the color parameter.

- Selected texture that is assigned to all samples that match.

This node is variadic, and more inputs with associated color indicies can be added.

## Outputs

The Select node generates a merged 3D texture.

## Parameters

The Select node accepts 2 parameters:

- A color index that is compared with the color index of each sample

- A tolerance value used when comparing the color parameter with the sample’s color index
