Quote - That's why there's a checkbox next to gamma correction - it's an option, not a requirement. Whatever gives you the result that you're looking for is the way to go.

And thank you very much for including that box.  :thumbupboth:  If you guys ever want to chase me away from Poser, get rid of that box and force people to use GC all the time.  That box is my friend.  It tells Poser that I meant exactly what I said, when I set up that shader.  I didn't mean give me some weird color that's vaguely similar, but not quite the same, then fight me when I try to work back toward the proper color.

Your post was civil and I'm just kvetching.  Can I ask, at least, why does GC change colors that I've entered as nodes?  I plug into a colorramp and GC changes what I've set on the node.  Shouldn't there at least be a selective OFF switch for that?  Without disabling GC altogether and thus having screwy lights?  There's something similar for texture maps.  Why not for specific nodes, or full materials?  So Poser will accept that I meant what I told it?

I'm kvetching again.  Sorry. I'm in a foul mood about other things and I'm transferring.  That's not fair.  You guys do good work, and GC is a great addition.  I have the sense, though, that it's doing a bit more than advertised.  In addition to compensating for monitor gamma, it's trying to fix that fact that Poser's lights have always been wrong somehow.  As a consequence, the entire materials flow of Poser is disrupted when GC is utilized, and presumably future rendering advancements will be GC-dependent.  It really looks like a feature that is only partially implemented so far, to me.  But I'm a know-nothing and a grouch.

Thanks for your help, Stewer, and everyone.  While I'd like to have the one or two actual questions I may have raised above answered, I'd also kind of like to let this thread die a death.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
