Hello,

I’m curious about the best practises around filtering out work items.

I can think of three methods:

• Use an expression of sorts in one of the filter nodes
  
• Pre-calculate whatever the filter criteria is and add it as a bool (int) attribute and filter by that
  
• Flag a work item as failed (maybe with a Python node and exception) and then filter on state
  

There may be others.

As with many things in Houdini there are lots of ways to achieve the same result, but just curious what folks consider a best practise?
