Edit a 3D Asset
For users who already have a model and need quick online adjustments before sharing, exporting, or using it in a prototype.
Upload and editEdit, 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.

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.
Continue in SEELE Workspace →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.
V7 demo: AI-generated model preview -> import break -> cleanup pass -> before/after -> upload generated model. The page does not claim SEELE integrates with any generator or replaces target-engine review.
The primary workflow: edit before generate.
Start from the 3D asset you already have. Edit, optimize, and convert it online before you export — AI generation stays available as a helper, not the starting point.
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.
Start from the 3D asset problem you already have.
Optimize a Game Asset
For heavy AI-generated models, store assets, or web game props that need lower polygon counts and smaller files.
Optimize modelConvert 3D Model Format
For moving between GLB, FBX, OBJ, and USDZ when you need a working file for your engine or web runtime, not a prompt box.
Convert formatClean Up AI-generated Models
For users who generated a model elsewhere and now need scale, material, topology, or export cleanup.
Clean up modelPrepare for Unity / Unreal
Frame the workflow around prototype readiness: scale, file size, material preview, export choice, and import guide.
Prepare assetUse in a Playable Prototype
An edited asset should become part of a playable scene, not stop at a file download.
Create playable sceneWhere AI generation belongs.
Generation is a helper, not the headline. Use it after your base asset is cleaned up.
- Generate a missing asset when your scene is ready but one prop is missing.
- Generate similar when the uploaded asset style works and you want variants.
- Generate matching asset pack when one edited model should become a consistent set.
- Start from prompt or image only when you have no model to upload.
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
An AI 3D asset editor workflow can help organize inspection, cleanup, material review, optimization, conversion, and handoff. It should not be read as proof that every mesh edit or production export is automatic.
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.
