Well I post the No mouth morph too, maybe it's usefull the way it its for you Pitklad or maybe somebody can fix it.

rayera you are right!
The morphs look weird on Domus... I hoped at least for the ear one but even that doesn't work...
I also use Zbrush but I couldn't come even close to your results... Which tool did you used?
Especially the ear morphs completely unwraps it... How can you do that  
I it isn't to complicated or a secret could you tell?  

I'll show you the process, it just take 5 minutes, it's a real honor for me to teach you something    

Width the Draw tool selected just press the SHIFT key, note that the pointer tourn blue and aply it over the ear

You'll end with it, you'll see a little bulge in the midle of the ear zone, too many vertices has gone to point

With the move tool stretch the vertices out

And smooth again with the Draw tool selectod with the SHIFT key using little touches, probably you'll need to use  Draw tool with ALT key (Zsub) with a small z intensity value too

There's someone behind you.

I'm shure you allready know it but the P4 figures are not quite simetrical, so the x symetry transform will not allways be a full help and maybe you'll ned to do some touches with it tourned off in the end.
Hope  I've been clear enough  

Wow!!!
Yhank you so much for the tutorial!
You are great!
some questions :
What difference makes the shift key? What is the difference of the blue color?
And also how you made Zbrush look so sharp... my always gets blurry when I zoom on my obj  
Is there any option to make the wireframe look more clear?

The Shift key put the Draw tool in smooth mode, its very versatile since you don't have to tourn it on on the menu and after use it tourn it off again in the menu like tha ALT key for Z sub the oposite of the draw tool, just release the key and you are in draw mode again, very fast, the blue cursos, I think is just the visual feed back to show you it's in smooth mode  
To Zoom in and out don't zoom the document, zoom the object, the shortcut key is: ALT + click on an empty space of the document, release ALT then drag up and down, don't be afraid the geometry of your object won't be scaled  
Hope it help you, and I'm not great    just tall (1.95 m, 80 kg)    

Oh yes you are the greatest!!!  
And too tall also!  
I have been using Zbrush all this time but always had that problem!
I thought the other zoom scales the obj too  
Your infos will make working much easiest!
Thanks again! Your examples are very usefull
I'll give it a try on those morphs as soon as the final head shape is ready
 
more previews soon!
 

    

Thanks for the tut rayera!            

Hi friends!
Sorry for joining in this late
I have been working with zBrush2 for creating morphs for Posette quite a while and am using a similar technique as rayera for smoothing down ( made a noNose for Posette some time ago and used it on my dino head for her excessively, both in our freebies). The only difference, I don't stretch the collapsed facets manually, I simply use the standard drawing tool to blow up this area again before the next smoothin steps, though I don't think it is possible to make the mouth disappear completely cos you cannot "close" the mesh. The geometry would have to be changed for this, and the morph would not work. In general I think you should use an already modified Domus head to create the morphs on and not the stock Dork for getting the best results.
Unfortunally, after reinstalling zBrush to my new computer I got some weeks ago,it refuses to accept my licence key , so i cannot work with this great program no more and have to learn an other modeller before joining in some serious morphing again I really miss it.
great work on the old boy, anyway! Can`t wait to see the results

Ahjah I've seen the no mouth morph in an old version of a character called Adam from Sixus1, So I thought it was posible,  I must search in my bad catalogued old CDs and try to find him to see how it was done    a hard tast believe me   , but now that I think beter probabli the inner mouth coul be used to fill the hole    I'll try it tomorrow, now it's late in this side of the world.
