LucyLive keeps Cinema 4D in control of the camera, scene, and motion while a remote generative model explores materials, lighting, atmosphere, and visual direction. It includes live viewport updates, composition locking, reference images, frame saving, and MP4 recording.

More examples

What is included

• The ready-to-install LucyLive plugin folder
• Pinned offline dependencies for the selected platform and Python 3.11
• No API keys, user data, renders, tests, or internal project files

Requirements

• Cinema 4D 2024–2026 with Python 3.11
• 64-bit Windows 10/11, or Apple Silicon with macOS 14 or newer
• Native Apple Silicon mode; Rosetta is not supported
• Internet access
• A compatible fal.ai API key, model access and account balance

Install

1. Download the ZIP for your platform and extract it.
2. Keep the complete LucyLive folder inside a folder used for Cinema 4D plugins.
3. In Cinema 4D, open Edit → Preferences → Plugins → Add Folder and select the parent plugins folder.
4. Restart Cinema 4D and open Extensions → AI Render.
5. Open Settings…, click Install deps, and wait for Done.
6. Restart Cinema 4D, add your fal.ai API key in Settings…, enter a prompt, and click Start.
7. Click Stop when finished.

Install deps uses Cinema 4D's bundled Python; no separate c4dpy, Command Line, or RLM license is required.

On macOS, make sure Open using Rosetta is disabled for Cinema 4D.

You can also provide the key through the FAL_KEY environment variable.

License

LucyLive is free to use in personal and commercial creative projects. You may share the official repository link. Reselling, mirroring, repackaging, redistributing the plugin files, and distributing modified versions are not permitted.

LucyLive is proprietary source-available, not open source. See the LucyLive Preview License for the complete terms.

Cloud processing and cost

LucyLive connects to the decart/lucy-2-5/realtime model through fal.ai. Prompts, viewport frames, and optional reference images are sent to external cloud services for processing.

As of August 4, 2026, fal.ai lists Lucy 2.5 at $0.04 per second (approximately $2.40 per minute) of processed video. Pricing and service terms can change, so check the current Lucy 2.5 page before use. Charges accrue while a real-time session is active. Always click Stop when finished.

If you choose Save key, the API key is stored as plain text in the local Cinema 4D preferences under lucy_live/config.json. On shared workstations, prefer the FAL_KEY environment variable and do not save the key in the plugin.

Do not send confidential scenes, personal data, or reference images unless you are authorized to upload them. Third-party terms and privacy policies apply; see the fal.ai Terms of Service and Privacy Policy.

Compatibility note

This is preview version 1.0.4. Windows is the verified platform. The native Apple Silicon package is experimental until the full Cinema 4D workflow has passed validation on physical Mac hardware. Intel Macs and Rosetta mode are not supported.
