When brands create digital humans, they often ask first if the model is realistic enough. Sustainable content depends on whether the character has a distinct voice, the team can produce at a consistent pace, and the audience believes the character makes ongoing choices.
The character must first have a defined scope of work.
Public case studies of virtual influencers offer a practical reminder. Once visuals reach professional standards, audiences shift focus from skin, hair, and facial details to what the character says, how it responds to the brand, and whether multiple posts feel like the same person.
Brands should first define the character’s identity, tone, acceptable topics, and off-limits subjects. Then decide whether it will host product content, engage socially, or serve solely as a visual avatar. Different roles require different models, voices, motion, and review standards.
Realism must serve the content context.
Film close-ups magnify minor issues with eye contact, lip sync, and skin texture. Social content differs in viewing distance, editing pace, and interaction style, so a character can succeed even with visible digital traits. Success depends on whether audiences can read its attitude and behavior.
This does not mean quality can be ignored. Facial distortion, dropped frames, and audio-lip desync still erode trust. Teams should first identify the acceptable performance range for the content, then allocate budget to details audiences actually notice.
Break production into reusable modules.
For digital human projects, manage character assets, motion libraries, voice rules, scene templates, and review checklists separately. This way, when scenes need to change for a new campaign, there is no need to recreate the entire video from scratch. When switching languages, it also clarifies which shots require re-performance and which can be reused.

Answer five questions before starting the project.
- Who is the target audience for this character, and will it serve as a shopping guide, explainer, companion, or performer?
- Which aspects of the character's speech, movement, and appearance must remain consistent over the long term?
- How much content needs to be produced weekly or monthly, and which workflows can be templated?
- What quality standards apply to close-ups, livestreams, short videos, and landscape ads respectively?
- Who retains and reviews authorizations for endorsements, likeness, voice, and training data?
Epic's current MetaHuman documentation integrates character creation, rigging, and animation into a single Unreal workflow. While suitable for technical validation, brand projects still require independent character design, content review, and version control. If you are preparing a digital human brief, please start with the ONCE Project Brief Portal to begin discussions.
