How To Build A Photorealistic 3D Clone

From modeling software to mobile apps, take advantage of these 3D cloning techniques we've provided!

The ability to inject a 3D model of an actor into your scene is valuable in so many different scenarios. You may have a dangerous sequence that wouldn’t even be financially or physically possible with a stunt double. You could also use a 3D model for complex VFX shots with 3D compositing, 3D camera movements, crowds or digital extras, narrative utility, and more.

Nowadays, creating a 3D clone or stunt double isn’t just easier than ever before, it can also be photorealistic. If you’ve ever wondered how to create a photorealistic 3D model of an actor, here are a few great techniques to get you started!

3D Face Scan with a Mobile App

This is hands-down the cheapest (and simplest) route for generating a 3D clone of a face. While there are a ton of mobile 3D scanning apps available, among the best are Bellus3D Face App (iPhone) and Bellus3D Dental Pro (iPad).
The scanning method is basically the same for each device, you simply follow the on-screen prompts and the app does the rest. Once you’re through with the scan, you can export as an .obj or .stl to bring into your modeling software for further refinement.

The currently supported devices for Bellus3D Face App are iPhone X, Xs, Xs Max, XR, 11, 11 Pro or 11 Pro Max, because scanning requires the TrueDepth camera. Note that the app can be downloaded on older iOS devices, but it doesn’t have the ability to scan per the developer’s app store listing.

If you’re a user of the late 2018 iPad Pro models, you can use Bellus3D Dental Pro.

Photogrammetry with DSLRs and Modeling Software

For more robust data capture, you can use a DSLR with stitching software to build a pretty accurate model.
For a more basic technique, something like Photoscan Pro can be used as in the video above, although do note that Photoscan Pro recently became Metashape and there are licensing costs to consider depending on the type of work you do.

For a highly-detailed, fully photorealistic model, you can turn to the video provided below. You’ll discover how to not only generate a high-resolution capture with a DSLR, but also how to refine the model significantly in several passes across ZBrush, Mudbox, and Maya to achieve a fantastically photorealistic model.  

If you’re interested in making the most realistic 3D clone or stunt double possible using photogrammetry, this is one video that’s well worth your time!
One of the key elements mentioned in the video that will allow you to add finer details is utilizing projection painting and skin packs. You’ll be able to create some truly impressive high-resolution clones!
