Quote -      I'll try to get some testing done.  Query:  Does this modify the pz3?  What happens if I get my materials set for gamma, then run the script, re-save the scene, then send a batch of test renders off to network remotes via Queue?   Essentially, the master sends a scene file to the remote, and the remote opens that scene and renders it.

Hm .. interesting pont!

What I do is find all the maps in the scene, grab the gamma settings for each one and store my findings as extra data in the scene file. When the scene file is re-opened the addon checks that extra data and updates the scene's nodes accordingly. That step won't occur when using the queue renderer.

So it will depend on at what point the bug manifests: at time of saving scene, or at time of loading scene ...

I'll be interested in your findings
