Game Asset Preflight Validator Pro — Blender QA & Export Tool for Unreal Engine and Unity

Game Asset Preflight Validator Pro is a professional Blender add-on designed to help 3D artists, game developers, and technical artists validate game-ready assets before exporting them to Unreal Engine, Unity, or other game engines.

Quickly identify production issues, improve asset consistency, and reduce problems caused by incorrect geometry, transforms, UVs, materials, textures, collisions, naming, and export settings.

Key Features:

• Asset Readiness Score (0–100) with errors, warnings, and blocking issues

• Geometry QA: triangle count, empty meshes, loose geometry, non-manifold geometry and boundary-edge checks

• Transform & Pivot Validation: rotation, scale, location and export sanity checks

• UV Validation: UV presence and lightmap UV checks

• Material & Texture QA: material slots, missing textures, empty image nodes and texture-resolution budgets

• Unreal Engine Validation: collision naming conventions including UCX_, UBX_, UCP_ and USP_

• Unity & Generic Validation: configurable rules for different production pipelines

• Collision Tools: quickly generate basic box collision geometry

• Automatic Fixes: repair common transform issues with one click

• Pre-Export Validation: validate your asset before FBX export

• FBX Export Workflow: export validated assets directly from the tool

• JSON & HTML Reports: create detailed QA reports for production and team workflows

• Clickable Issues: select the affected object directly from the validation results

• Configurable Budgets & Rules: adapt checks to your project's requirements

Workflow

Create / Import Asset → Select Engine → Run Preflight → Review Score → Fix Issues → Generate Collision → Validate Again → Export

Built for game-ready asset production, this tool provides a practical quality-control layer between Blender and your game engine, helping artists catch common problems before they reach the final export.
