Interactive 3D AI Character Animations -- 2

Freelancer Project Briefs — AI Character Marketplace App




BRIEF 1 — 3D Animated Character System Developer

Project Title:3D Animated AI Assistant Character — Web & Mobile App Integration

Budget Range:

Project Overview:

We are building a character marketplace app where users select, customise, and interact with a 3D animated AI assistant character. Think of it as a personal AI companion — a Pixar/Toy Story quality animated character that walks, talks, and gestures on screen in real time, inside a web app and mobile app.

We need a developer who can build the core character system: a real-time 3D animated character rendered inside a React web app (and optionally React Native for mobile), with a customisation system for skin tone, hair style, hair colour, and clothing swaps.

Reference Character:

We have an existing character design (Kayla — a 3D illustrated female character in athletic wear, Pixar-style quality). This is the visual benchmark. The final character must match this quality level. Reference image will be provided to the selected freelancer.

What We Need Built:

1.
Base Character Model

•
A rigged, optimised 3D character model in GLB/GLTF format

•
Pixar/cartoon-style 3D illustration quality (not realistic, not flat 2D)

•
Female and male base versions

•
Optimised for web/mobile: total file size under 8MB including textures

•
Compatible with standard Mixamo animation clips

1.
Animation Set

•
Idle (standing, breathing, subtle movement)

•
Walk cycle (looping)

•
Wave / greeting gesture

•
Talking animation (mouth movement synced to audio or looping talk cycle)

•
Pointing gesture

•
Thinking / listening pose

•
All animations as separate GLB clips or embedded in the model

1.
Real-Time Rendering in React

•
Embed the character in a React web app using Three.js or React Three Fiber

•
Character renders at 60fps on modern mobile browsers

•
Character can be placed on a transparent background (no background scene required)

•
Animations triggered programmatically (e.g., play "wave" when user opens app)

1.
Customisation System

•
Skin tone: slider with 6–10 preset tones

•
Hair style: swap between 4–6 preset styles

•
Hair colour: colour picker or preset swatches

•
Clothing swap: ability to load a different clothing GLB asset onto the base character (modular clothing system)

•
All customisation changes update in real time without page reload

1.
Clothing Swap Architecture

•
The character body and clothing must be separate modular assets

•
A clothing item is a separate GLB file that attaches to the character rig

•
Provide documentation on how to create additional clothing items to the same spec

•
This is critical — the clothing library will be expanded by third-party designers

1.
Photo-to-Clothing (Stretch Goal — bonus if included)

•
User takes a photo of a real garment (e.g., a shirt in a shop)

•
The system applies the texture/pattern of that garment to a base clothing template on the character

•
This can use an AI garment transfer model or a simpler texture projection approach

•
If this is outside your skillset, please note it and we will brief separately

Technical Requirements:

•
React 18+ / TypeScript

•
Three.js or React Three Fiber for 3D rendering

•
GLB/GLTF model format

•
Mixamo-compatible rig

•
Must run in Chrome, Safari, and Firefox on both desktop and mobile

•
No Unity or Unreal Engine — must be web-native

Deliverables:

•
Source GLB files for base character (male and female) with full rig

•
All animation clips as separate files or embedded

•
React component (<CharacterViewer />) that renders the character with animation control props

•
Customisation system as a React component with documented props

•
Clothing swap documentation and one example clothing item (shirt)

•
README explaining how to add new clothing items to the system

What to Include in Your Proposal:

•
Portfolio links showing 3D character work (especially web-rendered characters)

•
Examples of real-time 3D in React/Three.js if available

•
Your proposed approach to the modular clothing system

•
Estimated timeline

•
Whether you can include the photo-to-clothing stretch goal




BRIEF 2 — 3D Clothing & Accessories Marketplace Artist

Project Title:3D Clothing & Accessories Pack — AI Character Marketplace (Starter Library)

Budget Range:

Project Overview:

We are building a character customisation marketplace where users dress their AI assistant character with clothing and accessories. We need a 3D artist to create the starter clothing library — a set of modular clothing items that attach to our base character rig (GLB format, Mixamo-compatible).

This is ongoing work. The starter pack is the first order. If quality is good, we will commission additional packs regularly.

What We Need:

Starter Pack — 30 Items Total:

Tops (10 items):

•
Casual t-shirt (plain, male and female fit)

•
Business shirt (male and female)

•
Hoodie

•
Tank top / crop top

•
Polo shirt

•
Blazer / jacket

•
Sports top / activewear

•
Dress shirt (formal)

•
Oversized streetwear tee

•
Knit sweater

Bottoms (8 items):

•
Jeans (casual)

•
Dress pants / trousers

•
Shorts (casual)

•
Skirt (midi length)

•
Activewear leggings

•
Cargo pants

•
Mini skirt

•
Formal skirt

Shoes (8 items):

•
Sneakers / trainers

•
Heels (block heel)

•
Boots (ankle)

•
Loafers / dress shoes

•
Sandals

•
Running shoes

•
Chelsea boots

•
Slides / slip-ons

Accessories (4 items):

•
Baseball cap

•
Sunglasses

•
Handbag / tote

•
Backpack

Technical Specifications:

•
Format: GLB/GLTF, modular — each item is a separate file

•
Must attach cleanly to the base character rig (rig spec and base model provided)

•
Optimised for web: each clothing item under 500KB

•
Pixar/cartoon style to match the base character aesthetic — not photorealistic

•
Neutral base colour with a simple material setup (colour can be changed via code)

•
UV mapped so textures/patterns can be swapped (important for the photo-to-clothing feature)

Style Reference:

Pixar/Toy Story quality 3D illustration style. Clean, slightly stylised, not hyper-realistic. Think Fortnite character skins or Apple Memoji clothing — recognisable and appealing but not photographic.

Deliverables:

•
30 GLB files (one per clothing item)

•
Thumbnail render of each item on the base character (PNG, 512x512)

•
Naming convention: top_tshirt_casual.glb, shoes_sneakers.glb etc.

•
Brief note on how to recolour each item via material properties

What to Include in Your Proposal:

•
Portfolio showing 3D clothing/accessory work

•
Examples of low-poly or stylised 3D assets (not photorealistic)

•
Confirmation you can work to the GLB format spec

•
Estimated timeline for the full 30-item pack

•
Your rate for additional packs after the starter




POSTING TIPS FOR FREELANCER.COM

For Brief 1 (Developer):Post under: Programming & Tech → 3D Modelling → Three.js / WebGLAlso try: Mobile Apps → React Native if you want mobile-first

Search for freelancers with keywords: "Three.js character", "React Three Fiber", "GLB avatar", "VRM character", "Ready Player Me"

For Brief 2 (Artist):Post under: Design, Media & Architecture → 3D Modelling & CADSearch for freelancers with keywords: "low poly clothing", "game asset clothing", "GLB 3D assets", "Fortnite skin style", "stylised 3D character"

Budget tip:Post Brief 2 first — it's lower cost and lower risk. Once you have the clothing assets and understand the spec, Brief 1 becomes easier to evaluate because you can test whether the developer's character system actually works with your clothing files.
