Make a 3D Model Move to Your Song, Then Convert and Compress It

3D models puts a 3D model on your song. It opens with a free model already turning to the sample beat; press Play for the sample song, or choose your own under Music. It also runs as a tool inside Classic and Studio (Tools, then 3D Models), where the model becomes a layer of your project. Everything happens in your browser: nothing is uploaded.

1. Open a model

1. Press Open your model and choose the file. GLB, glTF, OBJ, STL, PLY, 3MF, FBX, Collada, VRML, X3D, OFF, USDZ and 3DS all open; an OBJ keeps its colours and pictures when you choose its .mtl and pictures with it, a .gltf needs its .bin. A ZIP of the model's folder works too, and so does dropping the files on the preview.
2. The check under it says how many triangles and surfaces the model has, its size, and what it found: holes, flipped faces, copies of corners.
3. Tick the repairs you want and press Repair the model: merge duplicate corners, remove empty faces, turn every face outward, store smooth shading, stand a Z-up model upright, centre it in a unit box.

2. Look and lighting

As made keeps the model's own colours and pictures, and Tint amount washes them toward your main colour. Studio clay, Toon, Chrome, Matcap, Hologram, Wireframe and Palette tint repaint it from your main and accent colours. Pick a lighting preset (Studio, Sunset, Neon club, Stage spot, Moonlight or Flat) and a backdrop; leave it Transparent to see the layers under the model in an editor.

3. Make the music move it

• Turntable turns the model a set number of times per bar, locked to the tempo.
• Bounce on kicks makes it hop on every kick drum; Scale with bass swells it with the bass; Glow with highs lights it in the accent colour with the cymbals.
• Wireframe pulse flashes its edges on every beat.
• Shatter on drops bursts it into its faces when the song drops and pulls it back together over two bars; Spin on new sections gives it an extra turn each time the song moves to a new part.

4. Camera

Choose Orbit, Push in, Crane, Dolly zoom or Still, then the speed, distance and height, and the model's size and tilt. Dragging the preview, the arrow keys and the zoom buttons let you look around without changing any of it.

5. Convert and compress

• Web small: The smallest GLB for websites and the editors: about 50,000 triangles, Meshopt compressed, pictures at most 1024 px WebP.
• Social post: A GLB a social 3D post accepts: under 3 MB, plain glTF with no extensions, pictures 1024 px JPEG.
• 3D print STL: An STL a slicer accepts: corners merged, faces turned outward, empty faces removed, standing on the floor.
• Keep quality: Every triangle and picture kept; the GLB is quantized to 16 bits and Meshopt compressed, usually a third of the size.
• Target file size: A GLB under the size you choose: pictures shrink first, then triangles, until it fits.
• Change the file type (GLB, glTF, OBJ, OBJ with its MTL in a ZIP, STL, PLY, 3MF or USDZ), the share of triangles kept, the picture size and type, or a size to fit under, then press Make the file. It says the size before and after and what it did, and Download saves it.
• For a GLB, Draco instead writes Draco geometry compression for the apps that ask for it; Meshopt is the default because it is as small or smaller and opens in the same apps.
• Convert as it is writes the model in another format without changing it.

6. Use it

1. In Classic or Studio, press Add to this project as a 3D layer. On the page, Open in Classic or Open in Studio opens the editor with the model on a new layer.
2. Download PNG saves the frame on screen; with a transparent backdrop the PNG is transparent too.
3. Make and download the loop writes a seamless WebM or MP4 of 2, 4 or 8 bars: the turntable and the camera are rounded to whole turns so the end runs into the start. Every long job has a Stop button.
4. Save to your library keeps the look and music settings to open again here, in Classic or in Studio.

7. The 3D library

The library holds 18 free models made for music, from a turntable, a speaker and a microphone to a crystal, a ringed planet and a neon ring. Press one to show it, or download it as GLB, OBJ or STL. The same models are on the templates page, and your saved 3D models are listed under Your 3D models.

8. The 3D layer in Classic and Studio

A 3D layer is drawn in the preview and baked into the export, moving to the project's song. Move, size and turn it on the canvas like any layer; select it to change its model, look, music and camera. Every number is also a layer setting, so you can keyframe it, for example to raise Shatter on drops only for the last chorus.
