Capabilities & Limitations


As the iClone Python API continues to evolve, limitations may expand or contract over time. Below are lists of iClone Python API's currently known limitations. This list is not exhaustive.

Inoperable Assets

The following items can not be manipulated and acted upon with Python scripting:

Unsupported Operations

The following operations are not available via Python scripting:


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.

Version 0.7

Load iClone Formats

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.


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.
