From what I can tell, setMorphValue() only works on fields that are specifically labeled as morphs in character files, and body hair falls under the skin category. You can try using presets instead for this. Could make a different preset for each stage of growth and then apply it with blendPreset(). I haven't actually tried this so it may or may not workStill learning, please be patient with my noob questions.
All good so far, but I wanted my slaves to either shave or grow a bush. I tried with both setMorphValue and modifyActorVar with the variable BHairThickness from 0 to 1 to no avail. Any ideas if this is even possible?
I tried dismissing the characters and then invite them again to see if the change reflects on the next scene load, but that didn't work either.
Edit: I also tried directly as Actor:BHairThickness = 0. Doesn't work either.
