Hunyuan Motion from one sentence, then preview the clip

A 3D animator who needs a human motion clip types one sentence in the browser and previews the motion when the job finishes. Sign in before the job can start. The Generate click checks credits: Fast uses 60 and Standard uses 80. If the balance is short, the credit purchase opens then. A daily claim adds 50 credits; from a zero balance, two claims cover one motion.

View GLTF files in your browser

This page opens a GLTF 3D model directly in your browser, with no installation and no upload. Choose a file from your device and it appears on a dark stage that you can orbit, zoom and pan. The model is read and drawn on your own machine by three.js through WebGL, so the file never leaves your device. It is a quick way to check that an export is intact, to inspect a mesh before printing or importing it, or to preview a file that someone sent you.

About the GLTF format

Full name
GL Transmission Format (JSON)
File extension
.gltf
What it stores
A scene described in JSON: meshes, materials, textures, skins and animations, usually with geometry and images in separate .bin and image files or embedded as base64.
Typical use
Web and real-time 3D, AR and VR, as an open exchange format maintained by the Khronos Group.
In this viewer
Opened with the three.js GLTFLoader from the single file you select. Materials and embedded textures are shown; animations are not played.
Good to know
Companion .bin and texture files cannot be loaded from one selected file, so use a .glb or an embedded .gltf.

What this viewer does

  • Opens the GLTF file you choose locally; nothing is uploaded.
  • Orbit, zoom and pan with the mouse or with touch gestures.
  • Centres the model and frames the camera automatically, with a reset button.
  • Fullscreen mode for a closer look at the geometry.
  • Shows the model in its stored pose; animations are not played.
  • STL and PLY meshes are drawn in a plain gray material, and PLY vertex colours are not displayed.

How to view a GLTF file

  1. Click the file picker and choose a GLTF file from your device.
  2. Wait a moment while the model is read and drawn; large files take longer.
  3. Drag to rotate, scroll or pinch to zoom, and right-click drag or two-finger drag to pan.
  4. Use the reset-camera button to return to the default view, or fullscreen for a larger stage.
  5. Press reset to clear the model and load a different file.

Supported 3D formats

This viewer opens glTF, GLB, OBJ, STL, FBX, PLY, VOX and 3MF files, and every format has its own page in the list below. If you need another format, the converter pages turn GLB, glTF, OBJ, STL, PLY and VOX files into glTF, OBJ, STL or PLY, also in the browser.

GLTF viewer FAQ

Is my GLTF file uploaded anywhere?

No. The browser reads the file from your device and it is parsed locally with JavaScript, so nothing is sent to a server. Closing or reloading the page discards the model.

Why does my GLTF model look gray or untextured?

STL and PLY files are drawn with a plain gray material, because STL holds no colour data and this viewer does not display PLY vertex colours. OBJ materials live in a separate .mtl file that this viewer does not load, so OBJ models appear in a default material. glTF, GLB and FBX materials are shown when they are stored inside the file.

My .gltf file shows no textures or fails to open. Why?

A .gltf file often points to separate .bin and image files. You select only one file, so the viewer cannot fetch those companions and the model may fail to load or appear untextured. Use a .glb file, or export the glTF with buffers and textures embedded, and select that single file.

How large a GLTF file can I open?

The tool sets no file size limit of its own. What works depends on your device's memory and graphics hardware, so very large or dense models may load slowly or fail, especially on phones. If a file is too heavy, reduce its polygon count in your modelling software and try again.

Does the viewer play animations?

No. Animation clips stored in glTF, GLB or FBX files are not played; you see the model in its stored pose. You can still rotate and inspect it from any angle.

Can I use the viewer on a phone or tablet?

Usually yes. On mobile browsers that support WebGL you can drag with one finger to rotate and pinch to zoom. Large models can exceed phone memory, so a desktop browser is more reliable for heavy files.

My GLTF file will not open. What can I check?

Make sure the file extension matches the real format and that the file is not empty or truncated. Check that WebGL is enabled in your browser, since the preview needs it. Try opening the file in the software that created it and export it again. For glTF, confirm that no external files are required.
