hi all 
is there a way to reverse the operation of a morph slider in the facial profile editor.

example being my base mesh was modeled with an open mouth I have shut and set the morph but obviocsley now its open at 0% and shut at 100%  not ideal  

Cheers
in advance

It's easy if you have mouth open driven with morph only. A little more complicated for morph/jaw bone driven slider.

You basically create 2 morph targets with mouth closed and opened.
Then delete mouth open face slider, import "closed" target and bake it.
Finally create a new mouth open face slider with "opened" target.

As I said, if the is a bone in a mix, then chances of success might be lower (CC might make a fuss). But still doable.
Your case might be different but here is Kevin where I preliminary reversed the mouth open slider and then reversed it back in a video.

Thank you, this is great 👍

EDIT:  Thank you for taking the time to show me that work flow, I think in my case it's not the answer as my mesh is custom and not cc.
the morph slider editor part of your solution only works on cc meshes (for know at least - reallusion I'm looking at you) 

but thank you I really appreciate you taking the time to look at my issue.

Yeah, when you said you imported character with mouth opened, I should have figured it's a Humanoid.

But for Humanoids you have 2 more ways to do it (since we cannot bake Face sliders at all, nor we can use morphs for Humanoids in CC).

The routine with exporting opened and closed morphs is the same as in the video, but then:

If you have a Bone driven Jaw morph, you simply go straight to Proportion and close the mouth with respective Jaw bone (might not be as precise).

If it's purely morph driven slider you can still bake it in iClone (if you have it).
That is create a slider in Morphs Creator based on "closed" target and then Bake it in Morphs Animator.
Before sending character to Morphs Creator you must delete all animations from timeline (even if it's just a pose on first frame).

This one might be hit and miss. Morphs Creator is very sensitive to mesh quality (single dissolved face or loose vertex might cause a problem)

Finally you delete slider and reassign with "opened" morph target as I have shown in video for any method above.

cool, I will give this a try.

Thank you
