Photorealistic 3D Virtual Avatar

I have a set of high-resolution reference photos and I need them transformed into a lifelike 3d avatar who will teach inside a web-based, real-time conversational app. The asset must look genuinely human—skin pores, believable eyes, subtle skin shading—because I chose a photorealistic style, not a stylised avatar. The body only needs enough structure to support seated or standing shots; the spotlight is on the face.

What I absolutely require is a production-ready facial rig that supports natural speaking: lip-sync visemes, jaw and tongue motion, eye blinks, slight brow movement and relaxed head turns. The character will be driven by an AI speech engine, so the rig has to perform smoothly at runtime in the browser.

Deliverables
• High-poly sculpt and an optimised, clean-topology game mesh suitable for three.js
• 4K PBR texture set (albedo, normal, roughness, etc.)
• Comprehensive facial rig or blendshape library covering English phonemes, blinks and subtle head motion controls
• Short demo: the professor avatar reciting an audio clip to prove lip-sync, eye and head movement accuracy
• Documentation outlining controls and any plug-ins or runtimes used and the model files in .gltf.

Experience with MetaHuman, Faceware, ARKit blendshapes or other real-time facial pipelines is welcome, provided the end result remains lightweight enough for the web. Share links to previous photorealistic, real-time characters you have built and rigged; once I see a portfolio piece at the level I need, I’m ready to move forward quickly.
