CC/iC Blender Tools (Installed in Blender)

An add-on for importing and automatically setting up materials for Character Creator 3 & 4 and iClone 7 & 8 character exports.

Using Blender in the Character Creator pipeline can often feel like hitting a brick wall. Spending potentially hours having to get the import settings correct and setting up the materials often with hundreds of textures.

This add-on aims to reduce that time spent getting characters into Blender down to just a few seconds and make use of as many of the exported textures as possible so that character artists can work in the highest quality possible using Blender.

• Round-trip/Unity export additions and fixes.
  • Added baking raw metallic and roughness values into textures, when no textures connected, when exporting.
  • Modifiers removed from eye parts when exporting that prevented exporting blend shapes.

• Blender 3.0+ subsurface scattering method set to Christensen-Burley, rather than Random-Walk, which does not work well with hair transparencies.

• Cycles hair anisotropy reworked.
• Cycles parameter tweaks:
  • Brighter iris settings for SSR eyes.
  • Hair subsurface reduced (May want to turn it off completely, there can be too many artifacts generated in the hair.)
  • Skin subsurface slightly increased.

1.1.7

• Cornea material detection crash fix.

1.1.6

• Baking add-on compatibility update.

1.1.5

• Character and Object operators (Character Settings Panel):
  • Add object to character, with parenting and armature modifier.
  • Convert and add materials to character to use with material parameters and export write back.
  • Transfer body vertex weights to object.
  • Clean up object and material character data.

• Some import/export folder logic changed to try and cope with project folder & files being moved.
• Added custom texture node baking on export to CC3, including baking bump maps into normal maps on export.
  • If nodes are used to modify (or replace) texture inputs to material shaders, those nodes can be baked into the texture channel on export. This assumes the mesh has a valid UV map.
  • Bump maps can be baked into normal channels. Typically CC3 will only allow Normal maps OR bump maps for a material, not both, so an option has been added to combine them into just the normal map.

1.1.1

• Fix to crash from multiple character imports from iClone.
  • Note: Exporting multiple characters in one Fbx from iClone to Blender is not fully supported.
  • Characters should be exported individually.

• Import/Export Interface simplified.
  • If character has Fbxkey then character is setup for editing. (i.e. Shapekeys locked to basis)
  • Otherwise (character is posed or has animation) character is setup for rendering.
  • Only Fbxkey character can be exported back to CC3.
• Optional Json and Texture write back for exports.
• Optional teeth rotation fix that affects some older generated characters when importing back into CC3.
• Bake on export function added to bake custom material nodes connected to master shader's texture map sockets into textures to include when re-importing back into CC3.
• Additional objects can be selected for exporting with the character, but must be properly parented and weighted with an armature modifier. Otherwise CC3 will ignore them.
• Some property and parameter fixes.

1.0.3

• First attempt at a single material parallax eye shader added. Which does not use SSR or transparency and thus can receive full shadows and subsurface scattering in Eevee.

1.0.2

• Fixed Eevee subsurface scattering settings:
  • Reworked shaders to allow for direct application of subsurface radius to Principled BSDF nodes.
  • Only the default values in the subsurface radius socket are used in Eevee rendering.
  • As such, Eevee does not support inputs to subsurface radius and so shader and parameter code needed to be re-written to accomodate this.
  • Cycles unaffected by this.
• Fixed node group upgrade code that incorrectly renamed existing node groups and did not properly replace old shader/node groups with new ones in existing blend files.

0.6.2

• Lighting setups set Cycles transparent bounces set to 50 to accomodate Smart Hair mesh density.
• Lighting setups do not delete existing lights or camera, but they will hide them.
• Material setup now properly detects Game Base objects (i.e. Converted to Game Base in CC3 before exporting to Blender).
• Each material now maintains it's own set of parameters.
  • Updating material parameters in linked mode will change the same parameters on all materials of the same type.
  • Updating parameters in selected only mode will only change the parameter for that one material.

0.5.2

• Parameter changes update only that parameter in the imported or selected objects materials.
• Fake anisotropic highlights add to smart hair shader. (Can disable in the preferences.)
• Fake bump normals can be generated from the diffuse map if there is no normal or bump map present. (Can disable in the preferences.)
• Animation ranges only changed if physics enabled.
• Build settings and material parameters separated into their own interface panels.
• Build settings now applicable by material and the object and material build types as detected by the add-on are exposed and editable so you can fix them if it gets them wrong.
• Material parameters are context sensitive to the currently active object and material.
• Material parameters grouped into sections.
• Detects smart hair material or normal hair material and only shows relevant parameters.
• Option in preferences to gamma correct smart hair colours so they behave more like the colours in CC3.

0.3.0

• Fix to hair mesh detection with new smart hair system.
