How can we support infinite variations in a game, as in the real world, while keeping resources under control? In ALIS, structural texture patterns are generated on the GPU at runtime, cached by identity,

The map shows how our pipeline sees raw data before generation - open data kindly shared by the OpenStreetMap community. The city uses real coordinates at 1:1 scale - about 14 by 13 km around the Empire

We move fast and efficiently by building our own automated tools. For example, a simple UI utility finds scene objects by name and by the materials they use - then performs bulk replace or reset across

Uncompressed textures quickly eat up VRAM, drop FPS, and break scene smoothness, so we strictly control their compression for stable performance. We pick the right format for each job: masks - single channel

Use one pipeline for many cities and world extensions: playable, deterministic, open source. Watch

We continuously run scenes and objects across different locations and scenarios to keep the project stable. In Unreal Engine we use profilers - GPU/CPU, Nanite and texture/streaming visualizers, plus

One of the key locations is an abandoned shopping mall, based on a real place. We conveyed an atmosphere of desolation and looting - silence, dust, and traces of haste. Rare resources may still be hidden

Previously, having many detailed objects caused sharp FPS drops and required manual LODs. Now Nanite renders highly detailed models in real time without manual LODs: the engine streams detail where the

The rhythm of the scene is set by a dynamic day-night cycle that runs on a combination of technologies - Lumen handles indirect light and reflections, VSM handles shadows, and post-processing polishes

To preserve variety in the environment without losing scene cohesion, it’s important to balance randomness and spatial harmony. We achieve this with flexible Foliage Type settings - a special asset that

To achieve clean, believable shadows, we use Virtual Shadow Maps (VSM). VSM computes shadows primarily where the player is looking: nearby areas render in high detail, distant areas are simplified and

In the game, we capture the atmosphere of people’s lives and carefully weave realistic household items into the residents’ stories. We show untouched, cozy comfort through family details, neat furniture,

Material Layer Blend - a principle for combining material layers that creates a lightweight, quickly tunable system for blending surface effects - whether paint, dirt, rust, or scratches layered on top

ALIS — World Reborn will be featured at PlayB3yond Indie Game Fest from September 21–27. Explore a survival world built from real places, where streets, routes, terrain, metabolism, vitals, inventory and

The first free playable build of ALIS is out for Windows. ALIS is an early single-player prototype — not a finished game. It reconstructs a real city district you can walk through, with a metabolism simulation

A free, open-source Unreal Engine 5 editor toolchain is available for developers working on data-heavy projects. The core idea is simple: change game content as plain JSON, and the editor-side pipeline

Unreality Layers Material Layers is a builder for creating complex materials from multiple layers that stack on top of one another.,, Each layer adds color, texture, or an effect, and we easily control
