Grabbit 2: Physics-Driven Level Design for Unity, Rebuilt From Scratch
Solo dev William Besnard has rebuilt his popular Unity tool as Grabbit 2, turning level design into a live physics sandbox inside the editor. The new version isolates its own simulation, auto-generates convex colliders in the background, and lets you permanently bake those colliders so they ship in your build without any Grabbit runtime code. Under the hood it fixes v1’s messier edges with robust cleanup, reliable Undo, and big-scene performance. Five dedicated modes cover selecting, creating, placing, arranging, and scattering props with believable physics.
CNA: XNA Reborn in Modern C++23 for Native Game Dev
CNA is a new C++23 reimplementation of Microsoft’s classic XNA framework, built for teams that love the XNA/MonoGame workflow but want native performance and toolchain control. It mirrors XNA’s core namespaces and patterns—Game, GraphicsDeviceManager, SpriteBatch, Texture2D—while hiding SDL/OpenGL/Vulkan details behind clean abstractions. Even in its early state, CNA runs most XNA samples and offers a familiar development experience. The post links to the CNA homepage, GitHub repos, sample projects, and a YouTube intro video so you can dive in quickly.
🧠 AI, Systems & Worldbuilding
Simple Boids, Complex Flocks: A Unity Swarm AI Tutorial
Learn how to make huge, believable flocks of birds or swarms of enemies in Unity using the Boids algorithm. This video breaks the behavior down into simple, tunable rules—like separation, alignment, and cohesion—then adds bounds control, obstacle avoidance, and smooth rotation on top. You’ll see how to wire everything up with prefabs, rigidbodies, and physics queries while minimizing allocations. The creator also outlines clear next steps to supercharge performance with data-oriented design and DOTS.
When Ideology Becomes Systems: Building Frostpunk 2’s Factions
Frostpunk 2’s lead narrative designer explains how the team turned abstract politics into concrete game systems. They began with four ideological axes and 24 theory-crafted factions, validating each against real-world movements before cutting down to eight readable, systemic factions. An overly complex dynamic ideology simulation—75 Blueprint graphs strong—was ultimately scrapped when players perceived it as “random”.
🌆 LLMs, Lighting & Profiling
From Prompts to Procedural Cities: LLMs Inside Unreal Engine
Unreal Engine 5.8 now ships with a free, open MCP server that lets large language models act as controllable assistants inside the editor. Epic shows how they wired LLMs into PCG using 80+ spatial “primitives,” examples, and skills to build everything from furnished apartments to a fully parametric city in about a day. All output is standard Unreal data—inspectable, editable, and deterministic.
Mastering Mobile Profiling: Unreal Insights vs Native Tools on iOS & Android
Unreal’s mobile product manager breaks down a practical workflow for profiling UE games on iOS and Android. Starting from Unreal Insights to locate engine-level issues, he shows how to move into Xcode and Instruments or Android Performance Analyzer, ARM Streamline, and Snapdragon Profiler for deep CPU/GPU, memory, and thermal analysis. Detailed examples cover GPU pipelines, shader compilation, big.LITTLE scheduling, and power rails. New Unreal Engine 5.8 documentation ties it all together so teams can reproduce the setup.
💰 The Business of Games
How Games Fake Light and Shadows: A Deep Dive with Taha Torabpour
Taha Torabpour joins Wookash Podcast to unpack the messy, fascinating reality of real-time lighting in games. Starting from how our brains perceive depth, he moves through unbiased and biased path tracing, baked lightmaps, radiosity, and finally to shadow maps as a general-purpose collision tool on the GPU. Expect concrete examples from Quake, Teardown, The Witness, and his own custom C engine—plus candid insights on debugging GPUs, dealing with APIs, and why “good enough” is the mantra of rendering.
From Mobile Giants to a $10M Indie Fund: How VCs Really Judge Your Game
Games‑only VC Daniel Mironov of VGames explains how they sift through hundreds of pitches to back just 1–2% of teams, and what really matters in a mobile or indie deck. He breaks down check sizes, timelines, and the retention/ROI signals that move the needle, plus why Turkish studios excel at killing “okay” games. The discussion also unveils VGames’ new $10M Indie Fund: project financing for PC/console devs with revenue share, no equity, and no IP grab.
