The iClone Python API helps you to extend and customize iClone, and more easily integrate it into a Python-based pipeline. It provides a bridge between iClone and Python libraries and Python tools. The Python SDK is built on top of the iClone C++ SDK, and you can access a subset of the iClone API from Python scripts and execute them in iClone.
The iClone Python API can do the following:
Character
Prop
Camera
Light
Std(G5, CC, etc.)
Non-Std
Non-Human
Transformation (RTS)

Capabilities
As the iClone Python API continues to evolve, additional capabilities will be added over time. Below are lists of iClone Python API's current capabilities categorized by version number. The lists below are by no means exhaustive.
This includes *.iProjects, *.iAvatars, *.iProps, and any number of supported file formats readable and writable by iClone.
Animate Props
RTS (Rotate, Translate, Scale) prop transformations, including playing their animation clips.
Animate Characters
Play motion clips and rotate joints of a character in FK mode (Forward Kinetic).
Morph Animation
Drive morph sliders and key morph slider values in the timeline.
Add audio to objects
Add or remove audio tracks to props and characters that can playback in real-time.
Adjust Materials
Adjust strength contributions per texture channel, UV settings, diffuse color, ambient color, opacity values, etc.
Camera Controls
Adjust focal length, angle of view, near and far clipping planes, etc. on any camera in the scene.
Light Controls
Control settings for direction, spot and point lights. Such as range, angle, falloff, attenuation, etc.
Device Input
Drive animations and object parameters with the keyboard, mice, joystick, etc.
TCP/IP
Drive animations and object parameters remotely with IOT (Internet of Things) from other computers, cell-phones, etc. Or, have iClone drive IOT with smart network connectivity for lights, doors, etc.
Get Events
Setup callbacks for iClone run-time events such as on load, on selection, on parameter value change, on set timer, etc. Useful for tasks that need to trigger following an event like adding newly created items into a list tree, deploying automatic settings on load, or driving corrective morph targets when certain combinations of morphs are activated.
Render Project
Write batch render scripts and specify target directories for output.
Custom UI Design
Use iClone's native UI classes, or extend beyond it with QT's Pyside2 to create buttons, forms, dropdowns, modal windows, etc.
Animation Keys
Set timeline keys for various motion clips. Animate props, characters, lights, etc. via scripting.

LocalTransform & WorldTransform
Fixed incorrect transform rotations for RIObject, RIAvatar, RIProp, RILight, RICamera.
RINode::WorldTransform
New WorldTransform for RINode; No need for the user to write a function to retrieve it.
Rkey
New RKey can be used to carry additional data such as Time, TransitionType, and TransitionStrength.
Material Component
Fixed kTime > kKey for the MaterialComponent; Besides setting the frame time, one can also set the Transition Type and Strength.
LoadImageToTexture
Ability to load texture images to any channel within a material accessible via Mesh > Material Name.
RIHikEffectorComponent
Established framework for the RIHikEffoectorComponent API and test case is provided (not yet implemented).
Ignore API
Fixed RAudio:SetAudioPtr and RScene:SetScenePtr not being ignored (currently the online documentation also has this problem).
RApplication class
New RApplication class can retreive registry related data and API version number. Test case has been added.
RIObject::SetParent(RIObject/RINode)
All classes that derive from RIObject also inherit the SetParent member function.
RIObject::LinkTo(RIObject, RTime)
All classes that derive from RIObject also inherit the LinkTo member function.
RIObject::Unlink(RTime)
All classes that derive from RIObject also inherit the Unlink member function.
RIFaceComponent::GetKey(args)
Used to retrieve the current time's Facial Expression, Eye, and Head key values. Usage: RIFaceComponent::GetKey(RTime, Head, LeftEye, RightEye, Morph, Custom, Bone, Weight)
RIFaceComponent::AddClip(RTime)
Adds a default Facial clip at the designated point in time.
RIFaceComponent::AddEyeKey()
Create a EyeKey under the Facial Layer.
RIFaceComponent::AddHeadKey()
Create a HeadKey under the Facial Layer.
RIFaceComponent::AddExpressionKey()
Create a ExpressionKey under the Facial Layer.
RIFaceComponent::AddVisemeKey()
Create a LipsKey under the Viseme layer.
RIObject::SetName(std::wstring)
Used to change the name of an object.
RIObject::GetPivot()
All classes that derive from RIObject also inherit the GetPivot member function.
RIObject::SetPivot()
Provides a way to retrieve the pivot point of a prop.
RIObject::GetBounds()
All classes that derive from RIObject also inherit the GetBounds member function.
Used to remove the Viseme key at the specified point in time..
RlVisemeComponent::GetVisemeMorphWeights()
Used to get the weight of each Morph of Viseme.
RlVisemeComponent::GetVisemeBones()
Used to get the Bone used by Viseme.
RlVisemeComponent::GetVisemeKeys()
Used to get the time of all Viseme keys, and return RTime as an array.
RlVisemeComponent::GetVisemeKey( args... )
Used to get the VisemeID and Weight of Viseme at a specified point in time. Usage: RlVisemeComponent::GetVisemeKey( RO::RTime kTime, RO::EVisemeID& eVisemeID, float& fWeight )
iClone 7.4x Open Change Log: 03/03/2019 - 04/29/2019
RO::EHikEffector
Provide the same number as the core Hik enumeration that is aligned with RLHumanIK \ RLHikDef.h (the old version was aligned to ICInterfaceEnumDef.h). This fix is applied to both LeftHandThumb and RightFootExtraFinger enums.
RO::EHikEffectorType enum(Translate/Rotate)
Provide settings for HIK effector translate / rotate.

Used to convert the input local space matrix into a matrix in actual wolrd space.
Modified RISkeletonComponent::GetSkinBones
Fixed the problem of not returning all the skin bones. The original method will only have 54 Bone (CC), but it should be more than this.
Modified RIProp::WorldTransform()
Fixed the faulty rotation problem. The original Rotation did not do Degree to Radian, which caused the calculated Quaterion to be wrong.
It is used to set the weight ratio of whole body ik when IK effector moves (0-1).
CVisemeComponent::TextToSpeech( args... )

Modify CVisemeComponent::ProcessTTS( args... )
private function Modify the language system to determine the system according to RO :: ELanguage. Usage: CVisemeComponent::ProcessTTS( std::wstring strContent, RO::ELanguage eLanguage, float fVolume, float fPitch, float fSpeed, std::wstring& wsWaveFilePath, RL::CArrayList< std::pair< unsigned short, unsigned int > >& kPhonemeDatas )
