This article explains why mobile games often use ASTC 6x6 instead of 4x4 or 8x8. It shows that a PNG’s file size does not reflect the final in-game texture memory, compares the quality and memory tradeoffs of ASTC 4x4, 6x6, and 8x8, and argues that 6x6 is a safe default because it balances image quality and compression. It also covers when to choose different settings by asset type, and points out that Max Size, mipmaps, and ASTC device support can matter even more than the compression ratio.

This article explains how multithreading differs between Unity Mobile and WebGL builds. On Mobile, C# threads, Task.Run, and Job System can run normally, while Web 6.3 is effectively single-threaded for C# and only uses main-thread execution for non-Burst jobs. In Unity 6.4+, Burst-compiled C# Jobs can run on worker threads if the project and server are configured correctly, including the right Unity and Burst versions, Web Player settings, HTTPS, and required browser headers. It also clarifies that async, Coroutine, and Awaitable do not create real threads, and recommends when to use Jobs + Burst, frame-splitting, or main-thread work for different tasks.

This article explains the Observer Pattern in Unity as a way to decouple game systems so one object can announce an event without knowing who listens. It covers the C# delegate and event basics behind the pattern, UnityEvent and its Inspector-friendly workflow, ScriptableObject-based event systems for cross-scene communication, and a global EventBus approach. It also introduces UniRx for more advanced reactive workflows, compares the pros and cons of each option, and warns about common pitfalls like forgotten unsubscriptions, ghost listeners, and event spaghetti.

This article explains what a Normal Map is in Unity and how it makes flat surfaces look detailed without adding polygons. It covers how Normal Maps work, why they usually look blue-purple, the differences between Tangent Space, Object Space, and World Space, and how to import, assign, and tune them in Unity materials. It also discusses creating Normal Maps from Height Maps, using them across Built-in, URP, HDRP, and Shader Graph, combining and blending multiple maps, mobile compression and size tips, common mistakes like wrong texture type or flipped green channel, baking from high-poly to low-poly models, using Normal Maps in shader code, and how they compare with Bump Map, Parallax Map, and Displacement techniques.

This article gives a full comparison of AWS S3 and Cloudflare R2, covering what each object storage service is, their main features, storage classes, pricing, free tiers, durability, availability, limits, and ecosystem integrations. It walks through real-world cost examples for e-commerce, backups, and video streaming, shows how to migrate from S3 to R2 with S3-compatible APIs and tools like Super Slurper and rclone, and explains when to choose S3, when to choose R2, and when a hybrid strategy makes the most sense.

This article introduces FMOD in Unity and explains why many game developers use it as audio middleware instead of Unity’s built-in Audio system. It compares FMOD and Unity Audio through practical cases such as UI clicks and gunshots, footsteps on different surfaces, engine sounds, and adaptive music, showing how FMOD lets Sound Designers work in FMOD Studio while Unity code only sends parameters like material type or RPM. The post also highlights FMOD’s benefits for workflow separation, memory and CPU optimization, and more dynamic, immersive audio, while noting that Unity’s default audio is usually enough for small hypercasual projects.
