GLB Scene Editor

Inspect a GLB or GLTF model in a browser, make lightweight scene changes, and export the result as a GLB.

What this tool does

This browser-based Three.js editor loads a local GLB or GLTF model into an interactive 3D scene. You can orbit, pan, and zoom the view, change scale and X/Y/Z rotation, apply the Smooth or Melt visual operations, optionally replace meshes with a loaded sub-model, and save a GLB copy.

Who this is for

• Artists and developers checking a 3D asset before using it in a project
• Students learning basic scene transforms and GLB/GLTF workflows
• Teams making quick browser-based presentation edits to a 3D model

How to use this tool

1. Click Load GLB and choose a local .glb or .gltf file.
2. Use the mouse or touch controls to orbit, pan, and zoom around the fitted model.
3. Adjust scale from 0.1–5 and rotation on each axis from −180° to 180°.
4. Use Smooth, Melt, or Reset to try the available scene operations. Load SubGLB first if you want to test mesh replacement.
5. Click Save GLB to download the edited scene.

Inputs

Inputs are local GLB or GLTF files, an optional sub-model file, scale, and three rotation sliders. The editor operates in the browser and does not provide a project library, persistent account storage, or a material and metadata editor.

Outputs

The output is an interactive 3D preview and, when export succeeds, a locally downloaded binary GLB. SubGLB replaces each mesh with a clone of the loaded sub-model; it is not a general-purpose scene merge or selective mesh replacement workflow.

Example use cases

• Verify orientation and approximate scale before sharing a 3D asset
• Create a quick altered GLB for a prototype or visual review
• Compare a source model with a smooth, melt, or sub-model treatment
