• Currently, adding a new imager requires the render to be restarted. It is, therefore, recommended to add imagers before starting an IPR session.
  • Denoiser imagers should be applied before post-processing imagers if the post-processing is introducing new features in the image (ex: bloom).
  • You should apply the imager_light_mixer before any denoiser imagers, as light AOVs won't necessarily be denoised by the denoiser.

Post-processing nodes called imagers operate on pixels before the output driver. Imagers can be chained together.

The following post-process/imagers are available below:

 

 

A shader terminal, arnoldImager is available in the networkmaterial (or networkmaterialcreate) and the normal materials. The first parameter assigns the imager to the driver and you can use NetworkMaterialCreate to create the material network and use the arnoldImager terminal.

imager_exposure -> arnoldImager

 

 

Set the material to the driver's input parameter
