# ArnoldImager

Assigns an imager. This is stored as an ai:imager option in Gaffer’s globals, and applied to all render outputs.

Tip

Use the layer_selection parameter on each imager to control which AOVs the imager applies to.

## user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

## out

The processed output scene.

## enabled

The on/off state of the node. When it is off, the node outputs the input scene unchanged.

The input scene

## imager

The imager to be assigned. The output of an ArnoldShader node holding an imager should be connected here. Multiple imagers may be assigned at once by chaining them together via their input parameters, and then assigning the final imager via the ArnoldImager node.

## mode

The mode used to combine the imager input with any imagers that already exist in the globals.

• Replace : Removes all pre-existing imagers, and replaces them with the new ones.

• InsertFirst : Inserts the new imagers so that they will be run before any pre-existing imagers.

• InsertLast : Inserts the new imagers so that they will be run after any pre-existing imagers.
