For this month, we will reveal some CC 3.1 features that are coming to you first as we prepare materials for CC v3.2 / v3.3 and the brand new Headshot plugin.

Character Creator 3.1 will be released the end of August.  As a 3D character creation hub, making good use of external and internal content assets is the key to help users create various characters. We adapted the editing tools in this version, so users can easily refine the external content for better use in terms of quality and performance.  The export capability to 3rd party tools including animation engines (e.g. iClone), and game engines (e.g. Unreal Engine, Unity) is enhanced in many ways, with remeshed iAvatar export, advanced customization settings on FBX export for different engines (e.g. Unreal hand and foot IK). 

As mentioned in the H2 Roadmap post, the CC3.1 updates can be categorized into four parts. 

• Seamless Content Conversion & Flexible Content Application
• Consolidate materials
• Weld vertices
• Cloth hide mesh tool
• New content format: AvatarPreset (updated; the best format to fast switch the whole character), iMaterialPlus, IES
• New Transformer profile: Poser HiveWire character, iClone G6 character
• Feasibility to Create Characters for iClone Animation with Visual and Performance Balance
• Remeshed iAvatar export
• iAvatar export with texture size settings on individual objects
  
• Game Pipeline Enhancement
• Enhanced FBX export options for Mesh, Motion, Mesh & Motion
• New material merge options for Game Base to keep good visual quality on eyelashes
• Custom features for Unreal Engine 4 and Unity
• Character Creator & iClone Auto Setup
• Compatibility: the auto-setup tools for UE4 and Unity will be officially compatible with Character Creator 3.1 and iClone 7.6
• Characters: automate the process of shader assignment, skeleton mapping, LOD deployment (CC3 only)
• Props: automate the process of shader assignment
• Mechanism of Update Notification:  once you update Character Creator to 3.1, and update iClone to 7.6 or any version above, an update notice will prompt upon program startup if there is a new release of the auto-setup tool.

*Items highlighted in yellow means that it's only available in the Pipeline edition. 
*Export features is not highlighted because it works with CC3 for iClone if there is 3DXchange installed.

We've selected some features for sneak preview.  Now, let's explore more!

New Transformer profile: iClone G6 character ( Pipeline Edition only)

Starting from CC 3.1, you can transform your standard G6 character and outfits by importing FBX files via the Transformer tool.

Why support G6 Characters for the Transformer?

Re-meshed iAvatar Export ( Pipeline Edition only)

You can adjust the polygon quality level and texture size when re-meshing an iAvatar.


For example, there are many characters in this scene. The main character in the front is standard CC character, while the background characters are re-meshed iAvatars.  
The total polygon count is 58K (triangles) and it consumes much less memory compared to a scene with the same amount of unmodified characters.

LOD Export File Structure Enhancement ( Pipeline Edition only )

Export FBX Unreal or Unity preset now includes all of the LOD meshes skinned to the same skeleton.  The auto-setup tool will be updated along with this change.

Below is a comparison of the structure between CC 3.04 and CC 3.1.

Unreal IK Bone Support for Unreal FBX Export Preset




Example: The blue man (with Hand IK) holds the gun at the right hand positions, while the orange man (without Hand IK) doesn't.

Very impressive list of improvements, looking forward to using them.

Yo, nice features, some very, very long-awaited...
Well, at least i assume that remeshed iAvatar to iClone works without export restrictions!

It is not clear to me if there any new features for cc3 without the pipeline or 3dx7

Keep a character's feet planted on uneven ground, and in other ways to produce believable interactions with the world

Really really hope that is for Iclone too!!??
