Overview

AssetSentinel is a Blender add-on that batch-validates FBX, GLTF, and GLB assets against engine-specific profiles and generates structured HTML + CSV compliance reports.

It is designed for technical artists, art leads, and marketplace sellers who need to review large batches of assets quickly and consistently.

AssetSentinel does not modify your source files. It imports assets into a temporary scene, performs analysis, then cleans up.

Installation

1. Download the AssetSentinel .zip file.

2. In Blender, go to Edit → Preferences → Add-ons.

3. Click Install… and select the zip file.

4. Enable AssetSentinel.

Access it in:

View3D → Sidebar (N) → AIS Tools → AssetSentinel

Basic Workflow

1. Select a Profile (Unity Mobile, Unity Desktop, Unreal Desktop, or Generic Marketplace).

2. Choose a folder containing .fbx, .gltf, or .glb files.

3. Click Scan Folder.

4. After scanning, click Export Report.

Reports are saved to:

/AssetSentinel_Reports/

What Gets Validated

Geometry

• Triangle count

• Vertex count

• Ngon detection

• Material slot limits

• Negative scale detection

• Unapplied transforms

• LOD naming detection (_LOD0, _LOD1, etc.)

Scale

• World-space bounding box dimensions

• Suspicious scale detection (too small / too large)

• Scene unit system and scale recorded in report

Textures

• Texture presence

• Missing external texture files

• Maximum texture resolution (when available)

Naming

• Spaces in object/material names (profile-based)

• Illegal characters (profile-based)

Report Output

AssetSentinel generates:

• Professional HTML report (color-coded)

• CSV summary for spreadsheets

• Top violations summary

• Worst offenders ranking

• Import failure explanations with suggested fixes

The HTML report is designed to be forwarded directly to vendors or team members.

Import Failures

If an asset fails to import:

• The scan continues.

• The asset is marked RED.

• The report includes:

  • Failure type

  • Suggested fix

  • Technical detail (expandable)

This prevents one corrupted file from blocking the entire batch.

Profiles

Profiles define validation limits such as:

• Maximum triangles

• Maximum texture resolution

• Maximum material slots

• LOD requirements

• Naming strictness

Profiles are JSON-based and can be customized by advanced users.

Performance Notes

• Handles large batches (100+ assets).

• Uses temporary scenes for safe isolation.

• Cleans up data between scans.

• No telemetry.

• No network calls.

• No external dependencies.
