For mid-to-senior engineers with an UE rendering background. The whole article uses, as a reference implementation, a runtime weapon-batching system shipped in a large FPS that has been live on mobile — walking through its overall flow, key technical choices, and implementation-level details: how to collapse a modular weapon assembled from a dozen parts into … Read more
Revision note (2026-09-30): This article records work from 2026-07-06. Early proxy designs, sample measurements, and evidence about the original algorithm are distinguished below. Pending work retains its historical validation scope. Later progress is covered in heightmap reconstruction and POI, Stamp, vegetation, and rock layouts. AI-Assisted Game Dev · Asset Reverse-Engineering Series, Part 4 · Scene … Read more

In the previous article, *AI-Native Game Dev · Reverse-Engineering a Game Character Model into the Engine*, I pulled the assets of a third-person shooter’s characters and monsters — meshes, skeletons, materials — out of its package files and into the engine. That article was about whether the assets could be imported, and imported correctly. But … Read more
Migrating a mature open-world RPG’s city runtime to UE5: the driving core, entities, crowd AI, smart objects, pathfinding, vehicles/traffic, cross-system readiness gates, and LLM-driven gameplay — source-grounded analysis plus a UE5.8 rebuild blueprint.

This is the second piece in the “How to Build an Open-World Game” series. The open world we took apart last time had its engineering center of gravity in “making the world move”—how to keep hundreds of NPCs and a hundred-plus vehicles alive at once, and moving in order. This time we switch engines, and … Read more
In the previous article, AI-Native Game Dev in Practice · From Asset Reuse to Experience Reuse, I made one argument: during the gameplay-validation phase there is no need to wait for finished art — one can reuse existing assets and recompose them with AI, bringing the gameplay up first in order to validate it. That … Read more
This is a linear walkthrough: follow one mesh asset through Nanite’s full data flow — how it’s processed offline into Nanite format (resource processing), and how that data becomes pixels on screen at runtime (the render pipeline). Depth is implementation-level, with file:line references at key points (based on a UE 5.7 source build of E:/Project/UE; … Read more
