How to Start a One-Person Game Studio in 2026

BiteMe Games shares the mindset and strategy that took them from “let’s try gamedev” in 2022 to five shipped games and going full-time. The core advice: see yourself as a studio, not a hobbyist, and plan on multiple small releases instead of one massive passion project. They walk through engine choice, realistic timelines, early visual polish, and using shorts and social media to test market interest long before launch. It’s a grounded, modern blueprint for surviving—and thriving—as a new indie dev.

From 40‑Hour Light Bakes to Milliseconds: id’s Real‑Time GI Revolution

id Software’s Thiago Souza explains how idTech 8 replaced heavy lightmap baking with a fully real‑time global illumination system for DOOM The Dark Ages and Indiana Jones. By combining cascaded radiance volumes, a compact spatial‑hash radiance cache, and aggressive temporal/spatial denoising, they cut bake times from dozens of hours per level to milliseconds per frame. The result is huge, dynamic levels running at rock‑solid 60 FPS on all consoles, instant feedback for artists, and much simpler lighting code paths.

Real-Time SSS with Path Tracing and ReSTIR: Film-Quality at Game Speeds

NVIDIA’s Omniverse team unveils a new real-time SSS solution that finally makes offline-quality skin and translucency practical for games and virtual production. They split SSS into a ray-traced single-scattering pass and a physically derived multiple-scattering diffusion profile, fixing the common artifacts on thin or curved geometry. A tailored ReSTIR integration further accelerates single scattering with minimal extra rays. The talk walks through the math, sampling details, performance, and real-world examples, from marble statues to complex digital humans.

Inside Unreal’s MegaLights: Stochastic Direct Lighting at Console Budgets

MegaLights is Unreal Engine 5’s new stochastic direct lighting path that lets artists use hundreds of fully dynamic, soft-shadowed area lights even on current-gen consoles. Instead of shadow maps per light, it relies on a fixed ray budget, history-guided visible-light lists, blue-noise sampling, and variance-aware denoising to keep noise and cost in check. A hybrid visibility pipeline mixes ray tracing over proxy and far-field meshes, screen-space rays, and virtual shadow maps, and the same approach extends to volumetric fog and translucency.
