GPT-6 Astra One-Shot a 3D Portfolio, Then Iteration Turned It Into an Explorable Browser World
beatomni · reddit · 2026-09-13
A developer one-shot prompted GPT-6 Astra to build a 3D portfolio — and it worked: character, world, projects, walkable. The first version felt toy-like, but days of rapid iteration turned it into an explorable browser world (loaflet.com) with custom project spaces, interiors, NPCs, mini-games, mobile support, graphics settings and Photo Mode — all live in-browser, no install. His takeaway: iteration is ridiculously fast, but you still have to be opinionated about what's worth keeping.
