Untold Engine

untoldengine

Hi, I’m Harold Serrano 👋

I’ve been building the Untold Engine, a 3D game engine I started over 12 years ago. For the past two years, I’ve been rewriting the entire engine from C++ to Swift, with a focus on performance, clarity, and modern graphics techniques.

Through this journey, I’ve gained deep knowledge of rendering pipelines, shader optimization, and engine architecture. I also share what I learn through devlogs and YouTube videos, where I document progress and break down technical challenges. You can find my devlogs on my personal website.

The Untold Engine strives to be a stable, performant, and developer-friendly 3D engine that empowers creativity, removes friction, and makes game development feel effortless for Apple developers.

By sponsoring, you help me dedicate more time to development, improve documentation, and produce devlogs and demos that grow the community. 🚀
