Original. Expressive. Customizable.

One character system.
Many ways to be you.

Friendly rounded proportions, a soft matte finish, and inclusive wardrobe and hair options. These PNG concepts illustrate the direction we’ll refine during the style test.

03 / Technical delivery

Designed for the browser.

Asset targets from your brief

  • glTF 2.0 binary (.glb), one file per piece
  • Shared humanoid skeleton and Blender sources
  • Under 30,000 triangles fully dressed
  • Under 500 KB per piece
  • Under 3 MB for base body with animations
  • Textures at 1024 px maximum per piece
  • Metal/roughness PBR and recolorable flat materials

Validation & compatibility

Check exports in glTF Viewer and a three.js preview. Review rig deformation, seams, clothing intersections, hat-and-hair fit, animation playback and file budgets.

Review the head from a three-quarter front angle for profile images. Representative phone and Chromebook checks will be agreed at kickoff.

Animation durations

Idle: 4s loop · Hero pose: 3s loop · Wave: 2.5s · Dance: 3s · Cheer: 2.5s · Celebrate: 3s · Think: 3s loop.

04 / Ownership & handoff

A clear scope from the start.

What does the $15,000 include?

The base character, all listed customization pieces, shared rig, seven animations, optimized GLB files, Blender sources and asset handoff guide.

Who owns the final work?

Final work follows the brief’s work-for-hire requirement: InterStock receives the final files, source files and rights for commercial use in the app, ads and partner promotions.

Does this include app development?

The fee covers 3D asset production and handoff. Customization controls, unlock logic, partner-logo switching code and production app integration remain with InterStock’s development team. Asset naming and rig requirements will be agreed at kickoff.

How will originality and inclusion be handled?

These AI-generated PNGs are visual concepts, not final 3D models or proof of browser performance. Production designs will be original and avoid resemblance to existing game or cartoon characters. Skin tones, hair textures and hijab options will receive equal design attention. Any AI use in final assets requires prior approval.

What do you need to begin?

The clickable mockup, style reference imagery, preferred export naming and rig requirements, plus nominated technical and creative reviewers.
