Well, it wasn't exactly what I meant (nor the OP, I believe). The sliders under the Gen Morphs are indeed there, but in previous Construction tools you also had the possibility to mess around with the NPC's face in the Character Screen's render window. It appears that bit is now gone and, with it, a whole lot of customization options.

@ H4vent: Yeah, someone pointed the thing with creating new races out earlier. I have fiddled a bit with that, but I still seemed to have very little control over the faces - exactly the same as when trying to edit normal NPC's, in fact. Maybe I went about it the wrong way, though. I'm still at a loss.

That's true, however those sliders only correspond to the same options you would find in-game. And modifying the faces still rely mostly on preset shapes of the head parts.

Edit: Made a custom race as a test. And for some reason the body disappears. I might've done something wrong, but I don't recall doing anything other than change the name and some stats. And the custom textures I thought I successfully assigned didn't show up either. I'll try again.

It looks like most of the character creation morphs are hard-coded. We can extend the number of eye/nose/mouth morphs, and create new race morphs. So far, I'm thinking that a creative set of "eye/nose/mouth" morphs could be used to add extra face shapes. Which might get messy, or lead to massively big files if everyone jumps in on this, and someone compiles a 'compatability patch' type of tri file.

Lots of good information here, I was searching for this myself last night and this morning, as I was trying to change the shape values for the High Elf race.

I noticed there is a glitch in editing the lip colour, I tried to go from default to a pop down menu list and it didn't change colour also tried custom ( which you use the colour palette ) and still no joy.
I do use the coverwomen mod however.

Also you can customise the colour of the skin, with the hair unfortionately are limited to beth's colours but not sure if that would change with the extended slider colour mod.

I couldn't find anywhere to change the head shape ( unless you make a new race ) Hair and eyebrows and eye colours all can change, just go to the bottom box click then the bodypart will show it the small rectangle box under and you just click then a drop down menu will show all the choices availiable.

I posted something about this yesterday, and it may be a related issue (sorry for hijacking the thread if it's not). I want to make a mod to vary the kids faces (they're all the same at the moment), but morphing the faces doesn't seem to have any effect. I can morph they advlts with the sliders but not the kids. Do you think this is intentional or just a bug? Kitty was saying earlier that the morphs are hard-coded so maybe Bethesda left out or forgot about the morphs for those face models.

Yes, I fear that not being able to edit children's heads (that sounded vaguely morbid) is intentional. Like Throttlekitty said, the headmorphs seem to be set and hardcoded. There will undoubtedly be workarounds for this (like Throttlekitty more or less suggested), but they'd be probably be too messy and convoluted to justify the effort.

Then again, I'm not an expert, so who knows what actually can and cannot be done, in the end? I'll keep an eye out for more news on this.

I never noticed that all the kids look the same, heh. Children don't have chargen morphs like the advlt races do, so that's why you're not seeing anything happen there. The only morphs they do have are for expression and speech. Unless there's some secret protection for children, I'm sure a ChildHeadChargen.tri could be crafted to allow for this.

What I meant about the hard-coded morphs is the morphs for Brow(H,W,D), Chin(W,L,D), Cheekbone(H,W), etc. There's no way (that I can see at the moment) to introduce new sliders or morph types, BrowInner up/down or BrowOuter up/down, for example.

So no manual shape customization? That...totally svcks . Oh well, I guess for now I'll resort to manually changing the shape of the headmesh through 3ds max. It may result in some unique look as long as it's used for custom race only. Otherwise it might have strange effects on existing characters.

I suspect introducing new morphs for custom races should not be a huge problem (although that's where my know-how completely ends). I'm a little disappointed by the lack of manual control over the head shapes, but I suppose it's not a total disaster; with extensive fiddling a more or less nice and/or unique look should be possible.

Thanks for the clarification, Throttlekitty
