Running NavMesh reachability checks in jobs with Unity’s NavWorld
Unity 6.6’s NavWorld lets jobs query loaded NavMesh surfaces and links, moving path checks off the main thread. The tutorial builds a reachability job that maps endpoints onto the mesh, searches with explicit limits, and rejects partial paths. A persistent search buffer provides reusable scratch storage, while AddDependency prevents the navigation world from changing during the job. It also shows how to extract path nodes and shared polygon edges for visualization or custom steering.
How to Bring ECS into a Live Game Without Rewriting the Engine
ECS can improve performance and make gameplay systems easier to extend, but bringing it into a shipped game means confronting legacy code, stable-pointer assumptions, and production constraints. This guide explains how unified APIs, careful memory compromises, and scripting integration can help ECS and existing systems coexist. The goal isn’t a dramatic rewrite—it’s a gradual evolution that keeps the live game running.
Performance & Visuals 🎮
How 2XKO optimizes stages for low-end hardware
2XKO's team optimizes its mostly static, forward-rendered stages for low-end hardware using separate CPU, GPU, and asset budgets, including a 6 ms stage GPU budget. CPU changes combine background characters into fewer skeletal meshes and move spline-following motion from Blueprint timelines to Niagara. A custom engine change lets fully opaque parts of translucent cards write depth to reduce overdraw. Automated performance tests, asset validation, and an in-editor texture memory checker help artists catch regressions and budget overruns during production.
Beyond Polygons: How Volume Rendering Brings Smoke and Fire to Life
Volume rendering turns 3D grids of voxel data into images, making it possible to visualize everything from scanned engine parts to medical scans. This introduction explains how voxels store properties such as density and how techniques like 3D texture slicing reveal the data. For game developers, the most exciting applications are realistic volumetric effects, including clouds, smoke, fire, fog, and fluids.
Better Animation Workflows 🎬
Brown Bag reduces animation handoffs with Unreal Engine 5.7
Brown Bag moved keyframe animation and shot production into Unreal Engine 5.7 to reduce repeated exports, imports and downstream revisions across five animated shows. Separate Sequencer tracks let departments work in parallel, while character subtracks split complex shots among animators. Blueprints expose Niagara effect controls for animators to keyframe, and vertex animation textures provide lightweight playback of simulations authored in Houdini. Real-time lighting helps teams spot issues earlier, but close-ups of dense white fur required path tracing after Lumen failed to deliver sufficient detail and self-shadowing.
