Hi,

First, explanation: let's say I have a figure like Victoria 4. I also have a head that I've modeled in another application. The vertices of the neck on the new head match up with the Victoria 4 figure
neck. So basically both heads can fit on her body.

So my question is: How can I create a file or preset that I can put in Poser or Daz Studio, and distribute online to friends and strangers, so that they simply click it and the new head pops in and replaces Victoria's head?

I think Aikotoon just uses alternate head geometry, but I'm not sure. So if anyone can explain the process or "behind the scenes" I'd appreciate it a lot.

Would Replace Body Part with Prop work?  (In Object menu) 
Haven't tried it myself, but it's a thought. 

Actually, what happens is that Aikotoon comes into the scene with the original aiko body geometry, but with the new toon head attached instead of the old.

Since it's against copyright to use her base mesh in the head distribution, somehow the head must be referencing her body and replacing it.

Doing the prop replacement is not going to work for this, unfortunately.

What you need is a INJ/REM Pose file in your pose library to do the trick.  Essentially create your morph, save the model as a CR2 and convert it to PZ2 for distribution.  Dimension3D has a Pose To Program which can perform the conversion and there is Injection Magic from DAZ3D.

The figure Satako came with INJposes to apply the head to different figures I believe... you could look it up in the store and see if the author could help you. Kirwyn uses an INJpose to establish geometry switching on the character "K" available in freestuff here. Please report back if you find anything out :)

I have used "replace body part prop" and then injected the appropriate morphs belonging to the prop but Poser doesn't always shade properly across the junction on the new mesh because of vertice order or something. I have always wanted a Poser 'Gilmore Girl" skinny scarf as a 'universal" neck join.

hborre, I'm not sure that's the way I should go. I'm not trying to do any morphs.. It's a completely new geometry. Then again, you're probably right :p

momodot, thank you, I will research those figures you mentioned and see if I can figure it out :)

Anyone is welcome to chime in still. :)

Here is what PhilC replied in another forum. Amazingly simple, once you know how :)
Thanks to PhilC for his help!

Open the Sydney CR2 file in a text editor.

Look for:-

actor head:1<br></br>
  {<br></br>
  storeageOffset 0 0 0<br></br>
  geomHandlerGeom 13 head<br></br>
  }

Replace with:-

actor head:1<br></br>
  {<br></br>
  storeageOffset 0 0 0<br></br>
  objFileGeom 0 0 :Runtime:Geometries:Your Folder:Your
Head.obj<br></br>
  }

Your Head.obj must be just the head and the vertices at the head/neck seam must exactly match the original head.

The original head morphs will not work but any new morphs that you create for the custom head will be OK. Poser automatically sorts out which morphs go with which head.
 

As an alternative to editing the cr2, you should be able to do the same thing by applying a pose file, e.g: { //Your Head.pz2 version { number 3 }

actor head
        {
        storeageOffset 0 0 0
        objFileGeom 0 0 :Runtime:Geometries:Your Folder:Your Head.obj
        }
}

I have tried this a few times, and it does work. I do seem to notice Poser slowing down somewhat when an 'objFileGeom' is applied via a pose file to a figure, and I assume that this slowdown also happens when the same change is made by directly editing the cr2, but I have not done any experiments to check this.

I'll be using this in the future, thanks for the info.
