Cookie Run: Oven Smash

[URP 17.3.0 / Vulkan 1.1.0] Glitches and flicker on Mali-G72 devices

Glitch Shader

UI Glitch Shader

VAT Outline

Skill-specific breakable object

A hit-feedback shader for AOs that are only destroyable by a specific skill, so the player can still recognize them as 'destructible' when struck with a non-destroying skill.

Animator State Clip Replacement Tool

A Unity editor tool that automatically reconnects AnimationClips assigned to a new skin code in the AnimatorController

Pack Textures To Array Tool

A Unity editor tool that takes multiple selected Texture2Ds and, with one right-click, auto-generates a grid PNG for Texture2DArray — including optimal grid calculation and automatic sRGB preservation. Category: Tool | Slug: pack-textures-to-array

Environment Mesh Optimization

Even background objects that don't take up much screen space affect the cumulative vertex count and rasterizer cost. This work organizes production rules for removing unnecessary edges and back faces based on silhouette, texel density, and camera viewpoint.

Splat Map / Normal Map Reduction

A pass that separates the tiling, tone correction, and boundary blending that splatmaps used to handle into Plane / Vertex Color / Alpha Decal — reducing the terrain shader's fixed texture sampling cost.

Animation Clip Reuse

Identified a bug where AnimationClips were duplicated proportionally to the number of characters in town, using Memory Profiler. Debugged the root cause (FxClipEventRuntime).

LOD Skin Weights Optimization

UI Rendering Structure Analysis

This pass separates UI always needed on the main screen from UI needed only by specific content. MainHud retains the basic UI, resources reused across screens are split into a shared Atlas, and UI used only in specific screens like Smash Pass / detail view / profile are organized into per-content Atlases. The goal is not to reduce the Atlas count at all costs, but to limit the UI texture footprint that the main screen always has to bear.

CPU profiling

Timeline shows CPU-bound, with the GPU idle.

Mesh Model Import Setting

Purpose • As LOD goes down (further away), options whose perceived-quality impact is small are turned off or compressed more, to reduce memory/data/risk, and to manage Import settings under consistent rules

Fake Shadow Guide

Uses Blob-style Fake Shadow. Purpose — improve in-game readability (Side benefit: fewer vertices drawn in the shadow pass)

Concept Art × TA Collaboration Guide

Shader NaN guards

Defended against NaN propagation from zero vectors / zero values in normalize / rcp / atan2 with a consistent pattern — blocking the mobile black-screen issue

Mitigating the Blitter duplicate-initialization error

Traced a Blitter duplicate-initialization error firing 137,080 times/day on Android down to its root cause via two-stage hypothesis verification.

Lobby dither

Analyzed the physics-engine cost of the dithering system that turns obstacles between camera and player translucent, and measured improvements along two axes — query method and computation cadence: PhysicsFixedUpdate reduced by 0.2–0.4ms, GC allocations reduced by ~30%.
