Godot 4.5.2: Critical Stability Update for Android, iOS, and PC Ports
Godot’s latest maintenance patch, 4.5.2, targets developers who can’t yet jump to 4.6 but still need critical fixes. It backports extensive rendering and platform improvements, notably fixing many Android Vulkan crashes, tightening D3D12 performance and reliability, and updating iOS Metal exports to default to A12-era hardware. The release includes 218 changes across the engine, editor, scripting, networking, and third-party libs. The team also notes 4.5’s shift to partial support, 4.4’s EOL, and encourages testing and donations.
Unity 6.4 Released: ECS Goes Core, Consoles Get Smarter Performance
Unity 6.4 is out, and while it’s not a headline-grabber, it quietly lays important groundwork for future engine evolution. ECS is now a core part of the Editor, Project Auditor ships built-in, and multiplayer devs get better Matchmaker logs, flexible CEL-based filters, and full config histories. Console teams benefit from Adaptive Performance on PS4/PS5/Xbox, with automatic quality scaling to keep frame rates stable.

Build Official Star Wars Experiences in Fortnite: UEFN Tools Go Live
Epic Games has unlocked official Star Wars creation inside Unreal Editor for Fortnite and Fortnite Creative, offering licensed characters, vehicles, weapons, and iconic locations like Hoth and Tatooine. Creators get three focused templates for combat, large-scale team battles, and narrative roleplay, plus new systems like decoupled Force powers and a Hero device to play as Vader or Palpatine. Niagara-powered VFX support cinematic space dogfights and hyperspace jumps. Published Star Wars islands must follow special IP terms, including a 20% revenue share with Disney and no in-island monetization.
TerraSplines: Non-Destructive Spline-Based Terrain Editing for Unity
TerraSplines by GRUELSCUM is a non-destructive terrain editing tool for Unity that lets you sculpt landscapes with splines without ever damaging the original data. Designed for stylized, cartoony worlds and rapid prototyping, it supports Height, Paint, Hole, and Fill operations with configurable global and local brushes across multiple terrains at once. Setup is straightforward—parent your terrains and splines, hit Find Refs, and start tweaking. TerraSplines requires Unity 2022.3+ and is actively maintained.

Towards CPU-Only SDF Games: Recursive Raymarching at 100 FPS
Signed Distance Fields make insanely flexible procedural worlds, but raymarching them has long been too slow—especially on CPU. This post introduces a recursive quad-based raymarching algorithm that advances groups of rays together, cutting SDF samples per pixel by 3–4x and more than tripling frame rate on a single M1 core. A second pass flat-shades up to 10×10-pixel patches when surfaces are flat, dropping below one sample per pixel. Paired with GPU cone marching ideas, it pushes fully SDF-rendered games toward real-time viability, even on CPU.
