I need a Mixed Reality experience that lets shoppers stand in front of their phone, tablet, or headset camera and see our products realistically overlaid on their body in real time. The goal is to drive retail and-e-commerce sales by giving customers the confidence that an item fits, suits their style, and moves naturally as they do. Core requirement • Virtual try-on for products – garments, accessories, and footwear should align with body tracking, respect lighting, and update instantly when the user changes color or size options. What I already have – 3D product models (FBX and GLTF) – Brand guidelines, color palettes, and reference imagery What I need from you – Scene setup in Unity, Unreal, or another engine you trust for MR that runs smoothly on iOS, Android, and, if feasible, HoloLens or Meta Quest – Accurate body, hand, or foot tracking (ARKit, ARCore, MRTK, or equivalent) – Lightweight shaders so the experience performs well on mid-range devices – A simple UI: product carousel, size selector, capture/share button, and “Add to cart” callback we will wire to our existing API – Clear build instructions and commented source so my in-house devs can keep iterating after delivery Acceptance criteria 1. Try-on alignment passes a 90 % visual fit test on three device types. 2. Average FPS ≥ 30 on an iPhone 12, Samsung S21, and HoloLens 2 test unit. 3. APK/IPA and source project compile without errors on the latest public SDK versions. Ideal timeline is four weeks from kickoff, but let me know what’s realistic for you. If you’ve shipped similar MR retail projects, send a short clip or link—seeing polished tracking and realistic shading will help us move quickly.
