Why we like it

Earns its place in the ScriptSpot library for its safety-first approach: it reports what will change before you commit, and even high-impact cleanups can be reversed through Hold snapshots and full backups.

What is Hierarchy Guardian?

Hierarchy Guardian is a 3ds Max tool built to analyze, clean, and validate complex scene hierarchies, especially those coming from Revit, BIM, CAD, SketchUp, and other external sources. Imported scenes often contain deep and chaotic hierarchies, technical placeholder nodes, broken group structures, inherited scale issues, and unstable transforms, problems that can later break animation, instancing, lighting setups, or downstream exports.

The tool follows a safety-first, analysis-driven approach. Before applying any change, it analyzes the scene and reports what will be modified, what will be preserved, and the estimated cleanup impact rated Low, Medium, or High. A protection system can automatically create Hold snapshots and full .max backups before cleanup, and you can restore the previous state or last backup at any time.

Cleanup covers hierarchy depth reduction, group-to-hierarchy conversion, removal of technical placeholders and dummies, and detection with optional fixing of inherited or corrupted scale. It preserves cameras, lights, proxies, XRefs, and instancing, and runs post-cleanup validation to confirm hierarchy integrity. Performance is optimized for large, complex scenes and heavy imports.

Who is Hierarchy Guardian best for?

Hierarchy Guardian is best for studios and artists working on ArchViz pipelines and large production scenes that import from Revit, BIM, CAD, or SketchUp.

How much does Hierarchy Guardian cost?

Hierarchy Guardian is completely free to download and use.

Key features

  • Pre-cleanup hierarchy analysis with structural diagnostics, reporting counts, depth, risks, and expected changes, exportable to a text file
  • Estimated cleanup impact rated Low, Medium, or High based on structural intensity, with a clear preview of actions before anything is applied
  • Preset-based cleanup strategies for CAD, BIM, ArchViz, and asset libraries
  • Safe hierarchy depth reduction with a configurable maximum depth, plus rules that prevent unsafe reparenting of multi-child nodes, meaningfully named, and sensitive objects
  • Removal of technical placeholders, dummies, and leftovers, robust group-to-hierarchy conversion, and detection with optional fixing of inherited or corrupted scale
  • Protection system for cameras, lights, proxies, XRefs, hidden or frozen objects, and animated or constrained nodes, with automatic preservation of instancing
  • Safety workflow with Hold snapshot and optional full .max backup, restore of previous state or last backup, and post-cleanup validation

Frequently asked questions

Does Hierarchy Guardian work with 3ds Max 2019?

Hierarchy Guardian is compatible with 3ds Max 2019 and later, so any version from 2019 onward is supported. It's built for professional ArchViz pipelines and large production scenes, with performance optimized for heavy imports and complex hierarchies. If you're running a release older than 2019, check the developer's page at Spline Dynamics before installing, since support is stated from 2019 upward. The version listed here is 1.0, updated in March 2026, so refer to that page for any newer details.

Can I undo a cleanup done by Hierarchy Guardian?

Hierarchy Guardian takes a safety-first approach to cleanup. Before applying any change, it analyzes the scene and reports what will be modified, what will be preserved, and the estimated impact. Its protection system can automatically create Hold snapshots and full .max scene backups before cleanup, and you can restore the previous state or the last backup at any time. Even high-impact operations can be reversed. After processing, post-cleanup validation checks for unexpected changes and confirms hierarchy integrity.

Is Hierarchy Guardian free to use?

Hierarchy Guardian is listed as free in this catalog. For current licensing terms and any conditions of use, check the developer's page at Spline Dynamics, since licensing can change over time. The tool is developed by rode3d for 3ds Max and, at the version listed here, targets professional ArchViz workflows with hierarchy analysis, cleanup presets, a protection system, and post-cleanup validation. Refer to the official page for the most up-to-date details on availability and any usage requirements.

Does Hierarchy Guardian handle scenes imported from Revit and CAD?

Hierarchy Guardian is built to analyze, clean, and validate hierarchies from Revit, BIM, CAD, SketchUp, and other external sources. Imported scenes often carry deep and chaotic hierarchies, technical placeholder nodes, broken group structures, inherited scale issues, and unstable transforms. The tool includes preset-based cleanup strategies for CAD, BIM, ArchViz, and asset libraries, safe depth reduction with a configurable maximum, group-to-hierarchy conversion, and detection with optional fixing of inherited or corrupted scale. It preserves instancing, constraints, cameras, lights, and proxies through cleanup.
