Protect certain parts from a morph?

in New Users
When I have a G8F for example and apply a head morph like the one of V8 and I'd like to keep the mouth so it stays the same as the base G8F. How can I do that?

You could use a weight map, either with X Morphs https://www.daz3d.com/x-morphs or just via attentuation in Morph Loader Pro, as long as it's a standard definition morph.
