Hi — the important part here isn’t just showing a 3D dog on screen, it’s building the cosmetics system in a way that still feels clean once you start adding more items, rarities, and future upgrades. Where these systems usually get messy is not the viewer, but item attachment and data structure — hats fit, collars fit, then skins or accessories start conflicting because anchors, materials, or equip rules were never standardized. I’d recommend Unity here over a WebView approach for better mobile performance and cleaner expansion later. I’d structure it around a cosmetic definition layer, slot-based equip logic, rarity/store metadata, and a lightweight inventory backend through Firebase or API. The part to get right early is how items bind to the dog model, because that affects every future cosmetic you add.

Building a robust, real-time 3D customization system with rarity tiers presents a fun technical challenge. I’ve previously developed similar cosmetic systems for mobile games using Unity, integrating with backend APIs to manage user inventories and item unlocks, ensuring performance on lower-end devices. I’m confident in delivering a system that mirrors the Rocket League experience you're aiming for, specifically handling the equip/unequip functionality and visual updates in real-time. Given the 7-day timeline, I estimate completing the core character viewer, item equipping logic, and basic store/inventory integration within that timeframe, focusing initially on Firebase for backend integration.
