Interactive AI Avatar– Realistic Human 3D Avatar -- 2

Project Overview

I’m looking for a highly realistic realtime 3D human avatar.

IMPORTANT:
The AI conversation system is already fully implemented on my side, including:

Gemini integration
realtime conversation pipeline
speech system
knowledge base
backend infrastructure

I do NOT need chatbot or AI development.

What I need is the avatar itself: a realistic human character with high-quality facial animation capabilities that can connect to my existing realtime AI stack.

The avatar will be used on a vertical screen for public-facing customer interaction.

Avatar Requirements

The avatar should:

look highly realistic and human
include upper body only (shoulders and above)
support head movement
support eye movement and blinking
support realtime mouth/lip sync
support natural facial expressions
include subtle idle animations
maintain eye contact naturally
run smoothly in realtime

The goal is to achieve realism close to MetaHuman quality, while still being optimized enough for stable realtime performance.

Technical Requirements

Looking for experience with:

realistic 3D human avatars
GLB / GLTF / VRM workflows
facial rigging
blendshapes / morph targets
ARKit-compatible facial expressions
visemes / realtime lip sync
NVIDIA Audio2Face compatibility
realtime rendering pipelines

Preferred runtime environment:

Three.js / React Three Fiber

The current system is web-based, so Three.js compatibility is strongly preferred.

Deployment Requirements

The solution must be self-hosted / owned by us.

We do NOT want dependency on external SaaS avatar services with recurring per-user or per-message pricing.

The avatar should be able to run:

locally on a Windows PC connected to the kiosk
OR
on our own AWS GPU infrastructure

The preference is for ongoing costs to come only from GPU/compute usage.

Avatar Style

The avatar should feel:

modern
realistic
friendly
polished
suitable for customer interaction

I’m open to:

MetaHuman
Character Creator
custom workflows
other professional avatar pipelines

as long as the final result is compatible with a self-hosted realtime workflow.

Nice to Have Experience

Experience with any of the following is a strong plus:

NVIDIA Audio2Face
MetaHuman
Character Creator
Ready Player Me
realtime facial animation
conversational avatars
digital humans
Three.js avatar rendering
Deliverables

Please provide:

final avatar model
facial rigging
blendshapes / expressions
lip sync compatibility
GLB/GLTF or compatible export
realtime-ready setup
demo/prototype if available

No AI backend development is needed.

Important

Please send:

portfolio
demos/videos
examples of realistic avatars or digital humans you’ve built

I’m specifically looking for someone with real experience creating realtime realistic avatars for interactive systems.
