Six 3D Avatars

I need six fully-fledged, hyper-realistic 3D avatar characters that I can drop straight into a health-data–focused application. These avatars will appear beside live metrics, guiding users through dashboards and interactive reports, so believable facial animation and natural poses are essential.

Style & Look
All six characters must read as real people: accurate human proportions, lifelike textures, and clean topology ready for high-resolution renders as well as real-time use. I do not want a cartoonish or futuristic aesthetic—photorealism is the brief.

Customisation Requirements
Each avatar has to support quick, intuitively swappable options so I can tailor them to different user groups:
• Changeable outfits (medical scrubs, smart-casual, sport wear, etc.)
• A library of facial expressions—from calm focus to friendly encouragement—that work with blendshapes/morph targets
• Accessory slots (stethoscope, smartwatch, AR glasses and similar)

Technical Expectations
Rigged for standard humanoid skeletons (Mixamo or UE5 compatible), with clean UVs, PBR materials and separate texture sets (4K). I’m happy for you to model in Blender, Maya or 3ds Max and deliver in FBX along with the original scene files. Please keep poly counts efficient enough for Unity/Unreal playback on mid-range hardware.

Deliverables
1. Six rigged FBX characters with default outfit
2. Outfit variants and accessories as separate meshes
3. Expression/morph target file or controller setup
4. 4K texture packs (base color, normal, roughness, metallic)
5. Quick start document explaining file structure and how to swap options

I’ll provide reference boards once we start; if you already have medical or wellness-app experience, tell me. Turnaround is flexible within reason, but clear milestones for previews, revisions and final delivery will help both of us stay on track.
