version .581 has this issue. Poser Software should be doing a hot fix soon that fixes this issue.

I was able to reproduce this effect in release version of poser. I could not duplicate it in debug. So I am now checking why release will not work properly.

Do any of these failed renders involve scatter volumes?

Blender has gorgeous NPR style options. It'll filter over to Superfly eventually, hopefully.

Now that would be a reason to switch to Superfly!

I did verify with the Poser devs that this is a bug that somehow got into poser 12.

I still believe there is a corruption in your installation that is throwing off the light color chip for some reason.  I am not noticing what you're describing, yet I am seeing some inconsistencies between nodes that I shouldn't be getting.  I'm hoping it's not a major bug in the Material Room.

I think I've isolated the problem to if you set the color of the light via the material room node "color" somehow the color picker is always adding a saturation to the color value. So you can never pick a gray.

But if you set the color of the light manually to a gray, the color node appears to get ignored and uses the value set. I recreated my lights since I noticed the default lights from poser do not exhibit this trait.

I did find I can edit my preset light file and set the values there and as long as I don't change light colors in the UI or bring up the material for the lights things seem fine.

Here are pics of what I do.

BTW, are you doing Firefly or Superfly renders?  I definitely do not see it in Superfly.  If you can screencap what you are seeing in the renders and the light node settings maybe we can visualize what is happening.

Well its not the material per say. Its basically the color of the light its just set as the material color in the color room or the color circle on the light. Poser seems to introduce a saturation value which then shifts the color. Maybe all lights need a little color and can't be 100% gray.

Well 12 didn't come with documentation that I can see. Usually that is in the content folder.

Moderators - this is an obvious 'troll thread' and should be locked.

How is this a troll thread. I'm just wondering why creators only make content for daz studio. I'm frustrated by the lack of poser content and see lots of cool stuff I'd like to have but its Daz only.

The big differences I have seen are:

1. TKinter is now tkinter.
2. Either use all spaces or all tabs, no mixing, easily fixed.
3. string.atoi and string.atof no longer exist and now its int(string) or float(string)

I posted a possible fix here. The python dir is missing dirs from the python 3 library. Plus Tkinter is now tkinter. I got most of my old scripts working.
