Edit, optimize, convert, export — in the browser

Free online 3D asset editor for game-ready models.

Use it as a GLB editor or online 3D model editor when you already have a file and need preview, optimization, format conversion, or a game-ready handoff. SEELE treats AI generation as a helper — useful when you need a missing asset, a similar variant, or a matching asset pack after editing.

AI model looks ready. Import still needs a cleanup pass.

AI model looks ready. Import still needs a cleanup pass.

Models from AI generators, marketplaces, or scans often look finished in the source tool but fail on import: wrong scale, broken materials, heavy meshes, or a format your game engine or web runtime cannot use. Run the cleanup pass here first.

  • Upload or import the GLB, GLTF, FBX, OBJ, STL, USDZ, PLY, ZIP, or converted package.
  • Preview scale, orientation, pivot, materials, textures, polygon count, file size, and any upload errors.
  • Edit, optimize, convert, export, or generate a matching asset pack only after the base asset is inspected.

The primary workflow: edit before generate.

Upload

Start from an existing GLB, GLTF, FBX, OBJ, ZIP, or AI-generated model file.

Preview

Inspect geometry, scale, materials, textures, and file size before changing anything.

Edit

Adjust scale, rotation, material direction, texture preview, and asset presentation.

Optimize

Reduce polygons, compress assets, prepare low-poly variants, and target faster web loading.

Convert

Move between GLB, FBX, OBJ, USDZ, STL, or engine-friendly export paths when supported.

Export / continue

Download, add to a game project, create a playable scene, or generate matching assets.

Where AI generation belongs.

What this editor does not promise.

No online 3D model editor can honestly call an asset “Roblox-ready”, “Unity-ready”, or “production-ready” without review. Treat the export as a prepared candidate, then verify it in your target:

  • Check scale, pivot, and orientation after import into Unity, Unreal, Roblox Studio, or your web runtime.
  • Review materials, texture paths, and polygon weight on the real file, not only in the preview.
  • Keep CAD repair, licensing review, and final engine QA in your own pipeline.

FAQ

Is this page about generation or editing?

Editing is the main goal. Generation is a helper for missing, similar, or matching assets.

Can I use this as a GLB editor for existing files?

Use this workflow to preview an existing model, inspect scale and materials, and plan the right optimization or conversion steps for its target workflow.

Which 3D file formats can I work with?

Start from GLB, GLTF, FBX, OBJ, STL, USDZ, ZIP, or an AI-generated model file, then convert and export toward GLB, FBX, OBJ, or USDZ depending on your target workflow.

Can I prepare assets for Unity, Unreal, or Roblox-style workflows?

Yes. Optimize and convert the asset here, then verify scale, materials, and import behavior in the target engine before calling it ready.

How does this connect to playable prototypes?

After an asset is edited or optimized, the strongest SEELE next step is to place it into a playable scene or prototype workflow.

Does an AI 3D editor remove the need to inspect the final model?

No. Inspect geometry, materials, textures, scale, performance, deformation where relevant, and the real target-engine import before release.

AI 3D editor: what the workflow can and cannot automate

Editor work to verify

Inspect topology, normals, UVs, material slots, texture paths, scale, pivots, polygon weight, and target-format behavior on the real file.

Where checklist guidance fits

Checklist guidance can help document review steps and handoff notes, but it does not replace direct file inspection.

What can the workflow automate, and what still needs review?

Direct answer: this workflow can organize diagnosis, supported edits, optimization, conversion, and export preparation in one place. You still need to inspect the real mesh, materials, texture paths, deformation, and target-engine behavior before release.

Free online 3D asset editor

Use an online 3D asset editor to inspect the real model, review geometry and materials, correct transforms, reduce unnecessary weight, and decide whether the result is ready for a web, game, or interactive prototype workflow.

For STL or print-oriented files, review units, normals, shell structure, polygon weight, and material gaps before treating the asset as game-ready. The safe promise is inspect and prepare; final engine import and production QA still need verification.
