Layer Selection

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]'
