  • 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.

 

 

 

Selection

Render

Specifies if an imager is effective only in the IPR, only in batch (e.g. Render to Picture Viewer, Commandline render, Team Render) or both. For example you can add imagers only to the IPR for look development, but turned off in the final render. Or vice versa, an imager may be slow or not required in the IPR, but turned on in final render.

Drivers

Specifies if an imager is assigned to all drivers or just the selected ones.

AOVs

Specifies which AOVs are affected by the imager.

  • all: All AOVs are affected.
  • beauty: Imager is visible only in the beauty.
  • expression: Imager is applied to AOVs selected by this expression.

Expression

Selects layers processed by this imager with a glob or operator expression. An imager can use a selection to determine what nodes will be selected to be processed by the imager at render time. The selection is an expression that can consist of multiple selections concatenated by: 

  • or (union)
  • and (intersection)
  • not (negation)
  • and not (exclusion)
  • () for nested scoping

 

Each selection uses glob patterns and regular expressions and a node will be processed by the imager if the expression matches the node name. By default, glob matching is used unless the selection is in a regex quote, i.e. r'<my_regex>'. For example:

(/group0/sphere* and not (/group0/sphere1 or /group0/sphere0)) or /group1/sphere3
 
not r'p(ickle|ringle)[0-9]+'
 
r'c(ar1|ar2)' or r'car[34]'
 


The following imagers are available below:
