From 150 to 1,000 Fish: Burst-Powered Boids in Tap Oceans
Unity developer Paulo Brandao from Superheart shares how a basic Boids setup maxed out at 150 fish before the CPU choked, especially on mobile. After switching to Unity’s Burst compiler, the team pushed that to around 1,000 fish with minimal CPU impact. The same project experiments with 3D procedural cave generation and underwater drones that control like jet fighters, complete with targeting, projectiles, and FX. The game, Tap Oceans, is also planned to have a browser-based version.
Goodbye Input Manager: How to Port Your Unity Inputs in Minutes
Unity 6.3 LTS deprecates the classic Input Manager, and this tutorial shows exactly how to move to the Input System without rewriting your whole game. Using clear one-to-one examples, it maps `GetKey`, mouse buttons, mouse position, scroll, and axis input to `Keyboard.current` and `Mouse.current`. It also covers replacing `OnMouseEnter`-style events with Input System pointer interfaces, plus the required PhysicsRaycaster and EventSystem setup. A practical cheatsheet for quickly future-proofing your Unity projects.

OpenUSD Core 1.0: A Common Language for 3D Worlds
The Alliance for OpenUSD has released OpenUSD Core Specification 1.0, the foundational “syntax and grammar” for a universal 3D language. The spec formalizes USDA, USDC, and USDZ formats and sets baseline compliance rules so tools can truly interoperate across simulation, digital twins, and world-building workflows. It also becomes the canonical reference for all future AOUSD standards. A 1.1 update, planned for 2026, will push into animation support and massive-scene scalability.
🤖 AI, Art & Online Platforms
No Opt-Out: Twitter Now Lets Anyone AI-Edit Your Art
Twitter/X has quietly added a one-click AI-edit button to every image post, letting anyone generate altered versions of your art with no way to opt out. Privacy and Grok settings don’t disable the feature, and even popular protection tools like Glaze and Nightshade fail against it. The only partial workaround—multi-frame GIF “images”—crushes quality and isn’t practical. For now, the article concludes the only real protection is not posting art on Twitter at all.
