Character Rigging | Conversational AI
Rigging that supports believable digital conversation
For conversational AI, the character often makes the first impression. If the face feels stiff, the body reads poorly, or the rig is hard to animate, the experience can lose trust before the conversation begins. Our character rigging service gives conversational AI avatars a reliable technical foundation for expression, movement and performance.
At Mimic Productions in Berlin, facial rigging and body rigging sit at the core of our workflow. We build rigs to support realistic animation, whether the end use is a branded AI assistant, an interactive character, or a digital persona. The aim is practical: give your team a character that behaves predictably, is ready for production, and fits the pipeline decisions that follow design.
Production challenges
Common rigging issues in conversational AI
Projects in this space usually fail when the character cannot support the interaction model.
01
Faces that cannot express enough
A conversational avatar needs more than a neutral pose. Without a strong facial rig, speech, emotion and subtle reaction timing can feel limited or artificial.
03
Handoffs that create extra work
When rigging is not planned around the next production step, animation and development teams spend time repairing the asset instead of using it.
02
Bodies that do not hold up in real time
Characters used in live or interactive contexts must stay stable in motion. If the body rig is fragile, pose limits are too narrow, or deformation is inconsistent, the avatar becomes difficult to use.
What your team gets
What this service helps you achieve
01
Readable facial performance
Blend-shape facial rigs support nuanced expressions for speech-led characters.
02
Flexible production scope
Rig complexity can be adjusted to suit the required level of detail.
03
Real-time friendly structure
Rigs can be prepared with game engine use in mind where needed.
04
Cleaner team handoff
A well-structured rig is easier for animators and technical teams to work with.

Production approach
Built around the way conversational avatars are used
We approach character rigging for conversational AI as production support, not a one-size-fits-all template. Facial rigging can be built to capture the character’s personality and support speech-driven performance, while body rigging provides the stability needed for movement, posture and interaction. Where detail matters most, wrinkle maps and carefully planned blend-shapes can add realism without overbuilding the asset.
Our team can support assets intended for real-time applications, including characters optimised for game engines such as Unreal and Unity. That makes the service useful for brands, studios and developers who need a character that can move from design into an interactive setting with fewer technical surprises. If your conversation layer is handled elsewhere, we focus on the rig itself and the handoff requirements that keep production moving.
For conversational AI projects, rigging choices affect more than appearance. They shape how a character reads during speech, how much nuance can be shown in the face, how the body holds up in real-time use, and how efficiently the asset can be handed to animation or development teams. We can build blend-shape facial rigs based on actor expression scans, add wrinkle maps for extra detail, and design body rigs for humans, animals or stylised characters. Depending on the production, we can also tailor the rig to suit budget, performance targets and delivery format.
This service suits teams planning an AI avatar that needs to look human, respond naturally and remain production-ready across many interactions. If you already have the conversational layer, we focus on the character side. If you are still defining the asset, we help shape the rig around how it will be used, so the result is expressive and usable.

How we work
How we approach a rigging brief
01
Review the character and use case
We look at the character design, intended platform and performance needs so the rig fits the conversation experience.
02
Define the facial and body scope
We decide how detailed the facial system should be, whether wrinkle maps are useful, and how much body flexibility the asset needs.
03
Build and refine the rig
Our team creates a production-ready facial or body rig and adjusts it to support the required range of motion and expression.
04
Prepare for handoff
We deliver the rig with the next production step in mind, so animators or developers can move forward with less rework.
Frequently asked questions
Frequently asked questions
Do conversational AI avatars need both facial and body rigging?
Not always, but most projects benefit from considering both. A face-heavy assistant may need detailed facial rigging first, while a character used in a fuller scene may also need body rigging for posture and movement. We help define what the asset actually needs, rather than adding complexity without purpose.
Can you build rigs for real-time use?
Yes. Our rigging services include character rigging and animation rigging optimised for game engines like Unreal and Unity. That makes the service relevant for interactive avatars and other real-time applications where performance and structure matter as much as appearance.
What is blend-shape facial rigging used for?
Blend-shape facial rigging allows a character’s expressions to be driven through a set of carefully modelled facial poses. For conversational AI, that helps the avatar show speech-related nuance, reactions and personality in a controlled, production-friendly way.
Can you keep the rig scope within budget?
Yes. Our work includes facial rigging can range from around 30 entry-level blend-shapes to 300 for film quality, but the right solution depends on the production. We can review the performance needs and advise on the essential blend-shapes to prioritise.
Does this service include the conversational AI system itself?
No. This page covers character rigging for conversational AI avatars. The conversational layer, such as chat logic or LLM integration, sits outside the rigging service. Our role is to provide the character foundation that supports the experience visually and technically.
What if we need more than a humanoid character?
The rigging pipeline can also support animals and mythical creatures. That is useful for branded characters or stylised conversational personas where the design is less literal, but still needs believable motion and clear performance.
