KIRA Universe is a transmedia entertainment platform, building browser-based games, music, films, cryptocurrency, gold / silver, merchandise, and more. I used a combination of Cinema 4D, Blender, Octane render, Claude, JavaScript, Squarespace, Meshy, Three.js - and many more tools, to build a fully playable world directly in your browser with no downloads required. You just visit the website and press play. KIRA Universe has had 3+ years of ongoing development, and continues building to this day.
