Inspect a model before the next asset step.
Use this page to verify a supported file in the 3D preview, then choose a separate editor, optimizer, converter, or generation workflow if the model needs changes.
Open a supported file
Start from GLB, GLTF, FBX, OBJ, or STL for viewing and inspection in the 3D preview.
Inspect the asset
Check scale, rotation, dimensions, materials, textures, geometry complexity, and file size without claiming edits or conversion.
Choose the next workflow
If inspection finds a problem, continue in a dedicated editor, optimizer, or converter; this viewer does not claim conversion or export.
Verified 3D viewer format support.
The SEELE workspace 3D preview is verified to open and inspect GLB, GLTF, OBJ, FBX, and STL files for viewing checks such as scale, rotation, geometry, and materials. Verified 2026-07-21 against the SEELE workspace 3D preview component, which maps these extensions to Three.js GLTF, OBJ, FBX, and STL loaders. Scope: viewing and inspection only — this page does not claim format conversion or export.
OBJ
Verified for viewing. Check geometry, grouping, and basic material assignment; OBJ carries limited material data compared with glTF.
FBX
Verified for viewing. Check geometry, hierarchy, and materials. Complex rig or animation behavior still needs review in the target engine.
STL
Verified for viewing. Check geometry, scale, and orientation. STL is geometry only: it carries no materials, textures, or scene hierarchy, so do not expect color or material previews from an STL file.

High-intent use cases.
Preview before engine work
Inspect scale, geometry, materials, texture expectations, and weight before committing the asset to a game pipeline.
Review before playable prototypes
Catch scale, orientation, geometry, or material issues before testing the asset in browser games, Unity scenes, Roblox-style prototypes, or WebGL.
Review AI-generated assets
Inspect generated models for scale, material, orientation, and geometry issues before opening a separate editing or optimization workflow.
Create matching variants
After editing or optimizing, generate missing props or companion assets in a similar visual direction.
Viewer-first asset checks.
Use the preview to inspect a supported 3D file before choosing a separate editing, optimization, conversion, generation, or playable-scene workflow.

Limitations and review notes.
Use this page as a viewing and inspection workflow, not as a promise that every uploaded or generated model is instantly production-ready. Review scale, materials, texture paths, polygon count, file size, and target-engine requirements before handing the asset to a dedicated production workflow.
FAQ
Is this a replacement for Blender or a full DCC tool?
No. This page covers online viewing and inspection. Editing, optimization, conversion, and export belong to the dedicated workflows linked from this page.
What file formats does this workflow target?
The SEELE workspace 3D preview is verified to open GLB, GLTF, OBJ, FBX, and STL files for viewing and inspection. This page does not claim conversion or export.
Why include AI generation here?
AI generation is a separate helper for missing assets and variants. This viewer page only claims supported file viewing and inspection; generation and editing continue in dedicated workflows.
Which 3D file formats are verified for viewing here?
GLB, GLTF, OBJ, FBX, and STL are verified for viewing and inspection in the SEELE workspace 3D preview, checked 2026-07-21. STL files show geometry only — no materials or textures.
Does this viewer convert or export between 3D formats?
No. This page covers viewing and inspection of GLB, GLTF, OBJ, FBX, and STL files. It does not promise conversion or export between formats; dedicated converter and editor workflows handle those jobs.
Practical 3D workflow questions
Use these answers to narrow the asset, format, platform, and review requirements before starting.
What can a 3D model viewer and editor do online?
A 3d model viewer and editor combines visual inspection with focused preparation tasks such as checking orientation, scale, materials, texture references, and file weight. It can support conversion or optimization handoff, but advanced sculpting, rigging, UV repair, and animation may still require a dedicated desktop DCC and final engine-specific testing.

A practical 3D model discovery and evaluation evaluation checklist
Use one representative input and follow it through edit, export, and destination testing. Treat “free” and “best” as search intent—not a promise about current access or quality.
What matters when comparing “model-viewer” options?
Define the subject, destination, format, and performance budget. Review rights, geometry, scale, materials, and runtime behavior before use.
What does a reliable 3D file preparation handoff require?
Searches mapped to this route include “3d model file” and “x_t file viewer”. Confirm the actual job and destination instead of assuming every wording is equivalent. Test mesh, materials, texture references, scale, rigging, animation, and destination import; document any data the handoff drops.
What does a reliable 3D model discovery and evaluation handoff require?
Searches mapped to this route include “model file” and “model viewer”. Confirm the actual job and destination instead of assuming every wording is equivalent. Judge a representative asset for rights, editable source, topology, textures, scale, format, and behavior in the intended scene.
Where does “viewer model” fit in the wider workflow?
Turn the phrase into an asset brief covering silhouette, detail, format, engine, and camera. Test the actual model, not its thumbnail.
