I have several shader nodes that I toggled animatin on for the AMBIENCE.   I played around with them and decided not to use them. They still show up now in the OBJECTS window under shader nodes as the ones I toggled on for animation.  I can't delete them.  On one I toggled the animate on/off - when I do I end up with duplicate shader nodes now in the OBJECTS window and ANIMATION window. But the animation (turning ambience on and off ) does not work anymore for this one that shows up a duplicate. 

How do I reset all of this for the prop I've been working on? I want to go back to where I was before I started messing with the animated shaders and not lose the other texture work I've done.  I tried saving as a prop and then bringing back into a new scene but all this mess returns with it.  

 Is there anyway easy to delete materials on a prop and create new ones with diff names? Thanks!!

Not quite clear, but I think the problem may be connected to the parameter
dials that Poser creates when you set a material value to Animated.  These
dials are on the BODY for a figure, or on the prop itself for a prop.  

When you later decide to set the material itself to non-animated, these dials
don't automatically disappear.  The best cure is to manually edit the PP2
file to remove these parameter channels.

A simpler method if possible:  Set the ambients to non-animated, and then save a
Material Collection.   Start with the "bare" prop (no materials) and apply
this Material Collection to it, then resave.

Thank you. If I wanted to edit the pp2 any best editor to use? Notepad and then do i just look for the shader nodes and delet out of there? I don't want to mess any of the other work in assigning groups and materials.  You're right. They don't automatically go away and because of this I have a conflict of some sort.....

Notepad is not good.  Better to use a "programmers editor" or at least
a line-based editor.  I think Wordpad will do it.

You want to look for paragraphs like this, beginning with shaderNodeParm:

        shaderNodeParm headlight_PoserSurface_6
            {
            name headlights
            initValue 0
            hidden 0
            forceLimits 1
            min 0
            max 1
            trackingScale 0.01
            keys
                {
                static  0
                k  0  0
                }
            interpStyleLocked 0
            }

Delete everything from the shaderNodeParm line to the bottom bracket
of the paragraph.  (You may have to count the ins and outs of the brackets
to be sure, if the paragraph isn't obvious.)

THanks!! that did it. Pretty easy in MS Word. Blasted them away all is well.....
