Hi everyone, here is a quick walk-through of quickly creating morph sliders using the new dialogue box from Character Creator v1.4



One of the new powerful feature introduced in Character Creator v1.4 is the ability to turn your creation into a "Morph Slider", in which you can either blend with other characters, or improve on it by tweaking the body parts to quick create a FAMILY worth of character content. 



You can import Character Creator compatible meshes in either:
  1.  OBJ format
  2. iAvatar format
  3. Using current character project already loaded in Character Creator
https://forum.reallusion.com/uploads/images/9313abef-e10b-47df-812d-be90.png



The process is fairly simple. I'm going to bring the old guy from above (also known as Winston) into Character Creator and turn it into a morph slider.



Go top the top menu, under Create, select Morph Slider

https://forum.reallusion.com/uploads/images/3404c8c4-4d0a-4c8a-aa1b-af20.jpg



A dialogue box should appear: There are a number of selections and input boxes, and I'm going to go through them one by one.


https://forum.reallusion.com/uploads/images/4407a128-d1d7-4f78-a700-d009.png


1. Set Category: 

This is the place where you can select which category your newly created Morph Slider will fall under in the Modify window. There are four choices: Body, Head, Eyes Teeth. I'm going to select Body since this is a full body character.

https://forum.reallusion.com/uploads/images/5606961e-b07b-41ca-9806-9829.png


2. Set Slider Path:


You can input the "Group" that your morph slider belongs to. For example, if I selected Body in the previous option and input Tokomotion under Slider Path, then the newly created slider will be in the Tokomotion Group

https://forum.reallusion.com/uploads/images/2bb7cb7d-9ec1-46cb-ae47-c4cf.png




3. 
Morph Name: 

Simply type in the name of your new Morph that will appear in the Modify window.

https://forum.reallusion.com/uploads/images/9c236230-2fec-498d-b631-4128.png



4. The Min and Max Morph Value: 

This sets the minimum and maximum ends of your new morph slider. 0 being the Source Morph, while 100 being the Target Morph (More on this later). Caution when setting a negative number for the Minimum value, as it may result in some really funky looking characters when you play around with the slider later! For simplicity's sake, I'm going to leave this in default. (0 and 100 respectively)

https://forum.reallusion.com/uploads/images/3b1429aa-1fd0-4c0a-bf51-c367.png




5. Thumbnail, select a thumbnail for your new Morph Slider.(Still in Testing)

You can load a 55 x 64 to 64 x 64 thumbnail pic here so that it will display along side the morph slider you have created.

We have included two template files which you can freely use. Find them under:

\Reallusion\iClone Character Creator 1\Image\Thumbnail_Template_Blank.png

\Reallusion\iClone Character Creator 1\Image\Thumbnail_Template_Male.png



6. Source Morph:

The Character Mesh that your morph slider will CHANGE FROM. You are essentially assigning the shape of the character that will appear as when the you set the Morph Slider value to 0

   There are three options:
   A. Default Morph (the one that loads to when you press the reset key in the Modify window)
   B. Current Morph (the shape of the current character as appeared in Character Creator
   C. File: The OBJ or iAvatar File 

   For this test, since I'm working with a default morph, I'm going to select default morph



7. Target Morph: 

The Character Mesh that your morph slider will CHANGE TO. You are assigning the shape of the character that will appear as when the you set the Morph Slider value to 100.

   There are two options: 
   
A. Current Morph (the shape of the current character as appeared in Character Creator
   B. File: The OBJ or iAvatar File 

   Since I want my character to morph from default character into Winston, and I happens to have a iAvatar file for this character, I'm going to select File and point to the right location.



This is what my final dialogue box looks like:

https://forum.reallusion.com/uploads/images/6bb794d9-8615-447b-b613-78f0.png



Other Settings:


8. OBJ settings:

    If you are importing from an OBJ file, you can set the Axis of your character depending on which 3D modeling application you used for further modification. If you are using an Character obj file that is exported from Character Creator, make sure you also load the accompanied checksum file (in .ObjKey format).


Auto Apply to Current Character:


This will automatically change your character's shape into the Target Morph which you have previously set.



This is the end result:

One of the coolest thing you can do is to mix and blend with other characters. 

If I load another character and turn it into a morph slider (In this case, Max, the strong dude), I can create new and exciting characters by simply adjusting sliders.

CC 1.4
does work only with OBJ and  with chksum fille.

https://forum.reallusion.com/uploads/images/fa7d98f8-5004-474d-a7d3-4e43.jpg

The "chksum file" you get only with the export from CC 1.4
i can not import a Obj from another 3D-Programm into CC 1.4 BlushBlushBlush

When you export your mesh from C.Creator as and obj file it generates also an obj.key file it is saved where you saved your export mesh.
When you start to load as a custom morph slider it needs this obj.key to activate it.

The Head-Morph-slider changed the hole Body not only the head.

A head-slider should only morphed the head !!!

yes i know this.
But only CC create this file not other 3D-Programm.
First you have always to export the Actor as OBJ by CC to get the obj.key.

Bump. It would be nice to have an explanation on this. There is no documentation outside of this post about this cuckery.

Why is a key file needed?

Why do you need a morph slider when you could just sculpt a model in ZBrush?

Why do you have to go through Character Creator to have a Crazy Talk 8 model?

Why does Character Creator not import normal FBX?

Is iClone 7 going to avoid these seemingly needless steps?

What is the release date for iClone7?

Is there going to be documentation written for these updates or are we going to have to ask endless questions until some kind soul makes a tutorial?

Thanks Eric.  Your instructions were straightforward.  If only it had worked.  It saved a cartoonish bodybuilder morph that was not even in use, along with the head morphs I wanted.  I tried it twice with identical results.
  • How to save only the desired morphs?
Thanks.  I look forward to your reply.
......................................................

OK, I think I get it.  Is saves ALL the morphs, both head and body, including any that were present in the base figure you used - not just the ones in the category you selected.  To save ONLY morphs for the head, it is necessary to RESET the entire figure before adding and saving head morphs.  Always start from zero.  Ha!

"Click the Export button to export two files, *.obj and *.ObjKey. The later one includes the      DRM data for the *.obj file. DO KEEP these two files because you will need it when you load      the modified OBJ Avatar back to iClone Character Creator as target morphing character."

http://manual.reallusion.com/Character_Creator/ENU/1/17_Export/Exporting_Obj_Avatars.htm


Why do you need a morph slider when you could just sculpt a model in ZBrush?


That would break the vertexorder. Like I say before it works only with CC Character Mesh as Morph nothing else

"DO NOT change the total number and structure of the vertex in the OBJ avatar                   by means of any features such as sub-division, slice,                   add/delete vertices... and so on."

That doesn't make much sense though, FBX is an interchange format. Why do you need to use Character Creator to use CrazyTalk, when you don't need it to use iClone? This seems to be a design flaw the software, not anything born out of logic. People who create for production are not going to use the character creator for much besides mockups. 

Who wants to resculpt things? It takes a few weeks to model some characters, this is not a fast process, and you need to be able to edit topology.

In this case, CC is the obj. Importer for the Morph target
The 3D CrazyTalk Head is nothing more than the RL CC Character Mesh.
You can only reshape the base CC mesh, as a morph target,  similar  DAZ Studio Genesis works. A uniform Mesh deform to  many Shapes.
