Optimizer – All-in-One Performance Toolkit

Polyzero Optimizer is a comprehensive Unity Editor toolkit that helps you

identify, diagnose and fix performance bottlenecks — without ever leaving

the Editor window.

Whether you're shipping for mobile, PC or WebGL, Polyzero guides you

from a full scene audit down to a one-click optimized build, with backups

and undo at every step.

WHAT'S INCLUDED

─────────────────────────────────────────

▸ SCENE ANALYZER

Single-pass scene traversal produces a 0–100 performance score with

colour-coded issues (Critical / Warning / Info), grouped by category.

Run in Scene-Only or Entire Project mode. Severity icons make the worst

offenders immediately visible.

▸ TEXTURE OPTIMIZER

Dry-run preview table shows every texture's current size vs. proposed

size before anything is changed. Applies max-size caps, compression

format and mip-map settings per profile. Per-platform overrides (Android

ASTC, iOS ASTC, Desktop BC7/DXT5, WebGL) with size-aware scaling based

on each object's visual importance.

▸ TEXTURE ATLAS CREATOR

Groups small prop textures into atlases automatically. Previews candidates

with a searchable list, remaps UVs and saves the combined material —

without breaking prefab references.

▸ MATERIAL SCANNER & MERGER

Finds duplicate materials by full property signature (textures, floats,

colours, keywords). Groups them visually and merges with one click. Search

filter lets you focus on a specific group instantly.

▸ MESH COMBINER

Cluster-based static mesh combining with full validation of rendering

properties (layer, shadow casting, lightmap, light probe settings).

Progress bar on large scenes with cancel support.

▸ MESH READ/WRITE OPTIMIZER

Safely disables Read/Write on meshes not needed at runtime — a common

source of unnecessary RAM usage that's easy to miss.

▸ LOD GENERATOR

Blender-style QEM decimation with UV seam, border edge and normal seam

preservation. Supports single objects and multi-target batch mode.

Adjustable quality per LOD level.

▸ AUDIO OPTIMIZER

Three profiles (Safe / Balanced / Aggressive) control compression format,

load type, sample rate and force-mono in a single pass. Preview estimated

size savings before applying.

▸ ANIMATION OPTIMIZER

Sets Animator culling mode and applies clip compression across all

Animators in the scene. Undo-safe.

▸ SHADER VARIANT ADVISOR

Estimates variant count per shader, flags keyword bloat and warns about

shaders that will generate large variant collections at build time.

▸ PARTICLE SYSTEM OPTIMIZER

Checks maxParticles, collision complexity, lights-per-particle and

culling mode across every particle system in the scene.

▸ FONT CHECKER

Audits Legacy and TextMeshPro fonts for dynamic font settings, estimated

atlas sizes and unused includes.

▸ BUILD REPORT ANALYZER

Reads Unity's last build report and surfaces the heaviest assets by

category with a sortable breakdown — no external tools required.

WORKFLOW FEATURES

─────────────────────────────────────────

▸ PRESET PROFILES

Five built-in profiles: Mobile, PC Balanced, PC Quality, PC High Quality

(4096) and WebGL. Export/import custom profiles as JSON to share across

your team.

▸ BACKUP SYSTEM

Every destructive operation creates a relative-path-preserving backup

before touching assets. Restore, delete or auto-clean backups older than

14 days — all from the Settings tab.

▸ UNDO SUPPORT

All operations that modify scene objects register with Unity's Undo

system so Ctrl+Z always works.

▸ PROGRESS BARS

Long operations (mesh combine, atlas creation) show a cancellable progress

bar. Always cleared cleanly on completion or error.

▸ DRY-RUN PREVIEW

The Texture tab shows exactly what will change — current px, proposed px,

compression change — with a Ping button to locate each texture in the

Project window. Apply only when you're satisfied.

▸ SEARCH FILTERS

Live text search in Materials, Meshes and Atlas sections to narrow down

large lists instantly.

▸ ACTION HISTORY

Every operation is timestamped and logged in the Reports tab. Copy the

full history to clipboard or clear it at any time.

▸ PRE-BUILD VALIDATOR

Hooks into Unity's build pipeline (IPreprocessBuildWithReport) and

optionally blocks the build if Critical issues are still open.

▸ BEFORE / AFTER COMPARISON

Delta visualization in the Reports tab shows what changed between two

analysis runs with colour-coded rows.
