MD Props is a significant leap forward in virtual actor-environment interactivity. As a new feature designed to complement iClone Crowd SIM, it lets artists breathe life into 3D environments, making simulations more immersive and dynamic than ever before.
Give Life to Props
MD Prop Tools give iClone characters the ability to interact with 3D environments. By replacing the proxy components with custom 3D models, MD props manifest into visceral objects that 3D actors engage with.

All manners of interactive behavior can be generated from just FIVE TEMPLATES representing the core of MD TOOLS.
- ACTIONABLE: The most frequently-used interaction type that initiatives a behavior from the interacting actor while responding with an animation of its own.
- STATE-SWITCH: Transforms an actor’s animation state from one to another. Each state includes its own idle loop and triggerable animations, such as standing, sitting on a chair, leaning against the wall, or indoor cycling.
- BI-DIRECTIONAL: Focuses on scenarios requiring two-point mobility. A common application is for characters to move between two designated locations, such as entering or exiting automatic sliding doors, or traversing a crosswalk.
- PORTABLE: Supports the movement of items from one placement point to another. This includes picking up an object, carrying it around while using it, and placing it back down in the same or different location.
- DOLLY: Allows 3D actors to maneuver a cart and drag a wheeled object like a luggage. Once activated, a designated character will approach the dolly prop, grasp its handels, and steer it along a custom path.

Intuitive Radial Menu
MD Prop takes user experience to the next level with its intuitive Radial Menu system. These menus are designed to be easily accessible, launched by a simple mouse-over or click. The radial menus offer a range of interactive options, all of which can be customized with multi-level command groups and assignable hotkeys for quick and efficient access.
This feature also introduces Self Interaction, where a 3D actor can be directed to perform personal actions like using a phone, looking around, or even smoking a cigarette. These actions are not only gender-specific but also adapt to the actor’s profile, ensuring realistic behavior.

Action List & Concurrent Behaviors
Action Lists support the chaining of multiple motions to extend action sequences. When the scene simulation is paused, individual Action Lists can be assigned to every character in the scene. Upon playback, all the appointed characters will move simultaneously according to their own set of instructions.

- Action List allows animators to chain multiple actions together, creating seamless sequences that can be assigned to individual characters.
- Concurrent Behaviors When the scene simulation is paused, individual Action Lists can be assigned to every character in the scene. Upon playback, all the appointed characters will move simultaneously according to their own set of instructions.
Prop Customization
Customizing an MD template tool is straightforward: simply replace the proxy objects with a 3D model of your choice. Once the prop appearance is finalized, you can assign new animations or adjust the actor’s associative movements with minimal tweaks. This includes repositioning reach target positions to account for hand placements and varying arm lengths, as well as adjusting the look-at point to focus the character on specific features of the prop.
- Replace Mesh, Assign Custom Animations

- Refine Entrance Position, Look-at Point, Reach Point

Object Animation
MD Prop offers robust tools for animating itself. Creators can freely move, rotate, and scale any 3D item, with additional options for object morphing and particle effects. Morph Animator in iClone allows for intricate morph animations, while PopcornFX enables particle effects for added realism. Additionally, texture UVs can be adjusted and scrolled to create dynamic visuals, and video textures can be used to mimic interactive slideshows or film sequences.


Reactive Crowd Behavior
Beyond just triggering interactive behavior from individual actors, the MD Prop system enables autonomous crowd behavior. Crowd characters no longer roam aimlessly; they can now gravitate toward points of interest and even explore various props around the scene. Groups or individuals can find a spot to sit, visit the vending machine, or gather around a busker show—unleashing endless possibilities for dynamic crowd interactions.
- Simulation Modes – Characters moving along paths or spawning in a zone have a probability of engaging with the surrounding MD props.
- Following Options – Groups can be instructed to wait on members engaged with MD props before proceeding to their next destination.
- Random or Initial Occupants – Predefine multiple positions to attract passersby to stop and participate in an activity, or characters can be designated to occupy specific positions right from the start.
- Enter and Exit Probability – Interaction with MD props can be regulated according to character types and probability scores. Engagement frequency for MD props can be specified. Common settings include random, never, or a finite number of interactions.

Smooth Motion Transitions
iClone “Turn to Stop” and “Multiple Entry” functionality simulate natural human behavior in approaching and engaging with a target prop. This includes slowing to a stop, making a turn, and approaching with measured pace, distance, and orientation. MD props take care of the rest with smooth and natural interactive motions that are tailored to the gender and characteristics of the interfacing actor.

Multi-Platform Export & Render
Exporting these creations is seamless, with iClone Auto Setup plugins available for 3ds Max, Maya, Blender, Unreal Engine, and Unity. Live Link support also allows for synchronization with Unreal Engine and NVIDIA Omniverse, providing a two-way workflow that’s essential for modern animation and game development pipelines.
