NC AI Showcases Multimodal AI Innovation at SIGGRAPH 2025

South Korea’s leading multimodal AI company, NC AI, will showcase its latest AI technologies at SIGGRAPH 2025, the world’s largest computer graphics conference, taking place from August 10 to 14 in Vancouver, Canada.

Established in 1974, SIGGRAPH is now in its 51st year and remains the most prestigious venue in the computer graphics industry, bringing together thousands of researchers and companies from over 100 countries.

At this year’s event, NC AI will present its groundbreaking AI technologies VARCO Animation and VARCO SyncFace, highlighting how artificial intelligence is transforming game development and content creation across industries.

VARCO Animation: Next-Gen Motion Builder Powered by AI

VARCO Animation is a next-generation motion-building platform that enables game developers to automatically search, generate, and combine character motion data using AI. Tasks that once required hours of manual animation—such as walking, running, or combat movements—can now be performed with simple text-based commands.

For example, by entering a prompt like “a character holding a bow climbing stairs,” the AI instantly generates a corresponding animation. The model also adjusts the motion to suit different character body types and generates smooth transitions and stylistically similar motions to create coherent animation sequences.

The motion search system has evolved far beyond traditional keyword-based approaches. In addition to natural language-based motion search, NC AI will demonstrate a “similar motion recommendation” feature, where the AI calculates motion similarities to suggest relevant actions. For instance, even if the word “gathering” is entered, the system identifies appropriate motions based on intent rather than relying solely on literal descriptions—surpassing the limitations of pre-scripted commercial animation tools.

These collected and refined animations can be packaged into game-ready animation sets, compatible with development platforms like Unreal Engine. The VARCO Animation feature is set to launch later this month as part of the VARCO 3D product line.

At SIGGRAPH, NC AI will operate two demo zones: the Showroom and the Playground. The Showroom will allow visitors to create and explore motions with simple natural language prompts, while the Playground offers a hands-on experience where users can combine motions in real time, building complete character animations just as they would in an actual game development workflow.

VARCO SyncFace: Real-Time Lip Sync and Facial Animation

Also debuting is VARCO SyncFace, a voice-based automatic lip sync and facial animation solution that generates natural expressions, mouth movements, and emotional cues—without requiring motion capture or extensive animator input.

Built on NC AI’s proprietary LLM and multimodal framework, SyncFace can synthesize not just language, but also intonation, emotions, and gestures—offering a deeply expressive and nuanced animation output. It supports multiple languages including Korean, English, and Japanese, and goes beyond conventional lip sync by rendering emotional flow and nonverbal expressions accurately.

VARCO SyncFace has already been benchmarked as competitive with global leaders such as NVIDIA, offering more natural and emotionally rich animations. It is compatible with Unreal Engine and is already being implemented in new game IPs under development.

At SIGGRAPH, an interactive demo will allow attendees to record their own voice and watch as a character’s facial expression and lip movement are generated in real time. This will provide an engaging experience for both B2B and B2C audiences, enabling them to parody movie scenes, experiment with ad scripts, or simply explore creative animation possibilities.

Redefining the Standard for AI in Content Creation

Younsoo Lee, CEO of NC AI, stated:

“VARCO sets a new benchmark for AI utilization in the media industry. It is not only streamlining content production, but also fundamentally transforming how content is created. With our proprietary VARCO LLM and top-tier VLMs, we aim to drive real-world impact across industries through advanced multimodal AI technologies.”

Beginning with SIGGRAPH 2025, NC AI will expand the external licensing of its VARCO AI solutions, aiming to extend their application beyond games into broader industrial and creative sectors.
