Free Unity Editor QA tool · no signup

Audit FBX models, textures and prefabs before release or handoff.

Scan Unity assets for missing references, material slots, model scale/read-write settings and oversized textures, then export a CSV report. Free, no signup.

What it checks

Fast non-destructive audit

  • FBX/model Read/Write settings
  • Importer Scale Factor values for review
  • Oversized source textures with configurable threshold
  • Prefab renderers with missing material slots
  • Missing MonoBehaviour references
  • Optional prefab collider-presence check
  • CSV export for handoff or review

The tool reports findings only. It does not automatically modify your project.

Free real-world test asset

Run this workflow on an actual game asset, not only a checklist.

The Fantasy Arcane Gothic Crystal Chapel is free on Fab. Use it as a zero-cost asset to test import, scale, materials, textures and your own Unity / Blender handoff process; if the style fits, the wider Knit of Shadows catalog contains matching paid architecture, props and dungeon assets.

New · October 1, 2026

Unity's official plugin now supports Grok Build.

Unity 6+ gets the same 30+ Unity-written skills available to Codex and Claude Code. Use the official guidance, then verify project-specific changes before shipping.

Focused resource hubs

Go deeper without searching the whole site.

Use the Unity hub for asset QA and production workflows, or the seller hub for listing, pricing and pack-planning tools.

Unity 6.0 LTS · October 2026

Still on Unity 6.0 LTS? Use the remaining support window to test the move.

Unity lists 6.0 LTS support through October 2026 and 6.3 LTS through December 2027. Back up first, inventory packages, then regression-test assets and builds in a migration copy.

Unity 2026 · official Codex plugin

Using Codex in Unity? Keep project QA in the loop.

Unity's official Codex plugin ships Unity-maintained skills for Unity 6+ workflows, but generated project changes still need project-specific checks for prefabs, materials, colliders, textures and platform constraints.

External publication & directory proof

Knit of Shadows has been published or listed outside its own site.

Independent coverage and resource listings give buyers and developers a way to inspect the project outside its own storefront. These are publication/listing references, not endorsements.
