• Currently, Arnold refreshes the IPR when a new imager is added. 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.

 An introduction video to imagers can be found here.

It is not possible to connect Maya nodes or other MtoA shaders to imagers.
