Unlocking the Power of Scan Data: 2DNAC’s Advanced Pipeline for Digital Double Creation

In the evolving world of 3D character creation, digital doubles are becoming the gold standard for films, games, and commercials. These lifelike replicas of real people blur the line between reality and animation, delivering an unmatched level of realism. At 2DNAC, we are at the forefront of this technology, leveraging cutting-edge scan data to create digital doubles with meticulous accuracy. This post delves into our unique pipeline and the role scan data plays in crafting characters that are indistinguishable from the real thing.

Why Scan Data Is the Future of Digital Doubles

The essence of a successful digital double lies in its ability to mimic not only the look but also the subtle movements of real-life actors. That’s where scan data comes into play. Our pipeline at 2DNAC focuses on capturing high-quality scan data—down to the smallest facial features—to ensure that the digital double’s performance is lifelike in every frame. With our experience and technology, we are pushing the boundaries of what’s possible.

Key Elements of 2DNAC’s Scan Data Pipeline

1. The Data Acquisition Phase: At the core of our pipeline is a highly sophisticated scanning process. We use a combination of photogrammetry and custom tools to capture an actor’s face and movement. Using eight cameras, we gather a massive amount of data, including over 40 different facial expressions to ensure we can replicate every possible movement.
2. Real-time Processing and Optimization: Once the data is acquired, it’s processed in real time using our in-house tools and proprietary software. We emphasize clean, accurate data that doesn’t lose fidelity when transferred into various formats for games, cinematics, or commercials. This step is crucial, as it sets the foundation for how closely the final digital double will resemble the original actor.
3. Customization and Adaptation in ZBrush: Although the scan data provides the base, not all characters require a one-to-one replica. Sometimes, the data needs to be adjusted to fit specific creative needs—whether that’s making the character appear older, skinnier, or even more fantastical. Our team customizes the digital double as required, fine-tuning features with ZBrush to get the perfect balance between realism and creative vision.
4. Blendshape Techniques and Motion Replication: To ensure that our digital doubles not only look the part but also move with human-like fluidity, we integrate advanced blendshape techniques. These blendshapes are created by analyzing the scan data and modeling the muscles and skin of the face to respond naturally to expressions and speech. Our unique approach ensures every smile, frown, or raised eyebrow is captured accurately.
5. Integration with Unreal Engine for Real-Time Performance: 2DNAC’s digital doubles are rigged and animated using Unreal Engine’s powerful real-time rendering. This allows us to deliver characters that not only look great in pre-rendered cinematics but also perform seamlessly in real-time environments, such as AAA games and virtual productions. Many customers utilize MetaHuman rig, which we also support, but our primary focus is working with custom rigs tailored to their specific needs.
6. Final Look Development and Quality Control: Before any project is delivered, we go through a rigorous quality control process. Whether it’s tweaking eye movements or refining the skin textures under different lighting scenarios, we ensure our digital doubles are flawless. This process involves testing the digital double in multiple lighting environments and using custom tools to make adjustments as necessary.
