MOT to COLLADA Converter
FileFlip converts MOT to COLLADA entirely inside your browser, using Assimp compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a MOT file to COLLADA?#
- Drop your MOT file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to COLLADA and the conversion starts on its own. FileFlip downloads 11.2 MB of WebAssembly the first time and nothing after that, then runs Assimp on your own machine.
- Save the COLLADA file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting MOT to COLLADA lose quality?#
Not in the sense of pixels or samples. Converting MOT to COLLADA rebuilds the file in COLLADA's own model rather than re-encoding it, so everything COLLADA can represent comes through exactly and anything it cannot has to be dropped. Expect the geometry to be exact, and anything the target has no place for, such as a rig, to be left behind.
Is it safe to convert MOT files online?#
Yes, because nothing is uploaded. FileFlip converts MOT files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What MOT to COLLADA actually does to the file#
Converting MOT to COLLADA runs on Assimp, downloads 11.2 MB of WebAssembly the first time and nothing after that, rebuilds the file in the target's own model.

What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Materials | Sometimes | Survives for some files and not others. |
| Textures | Sometimes | Survives for some files and not others. |
| Skeleton and animation | Sometimes | Survives for some files and not others. |
What is a MOT file?#
A MOT file holds NewTek LightWave motion data, the position, rotation and scale keyframes for a single item saved out from a scene so they can be applied to a different item.
Save motion as MOT when a keyframed animation needs to be reused on a different item inside LightWave.
Convert MOT to FBX or glTF animation data once the motion needs to drive a rig outside LightWave.
What is a COLLADA file?#
A DAE file is an XML document in the COLLADA schema, created at Sony Computer Entertainment in 2004 and now maintained by the Khronos Group, describing a 3D scene's geometry, materials, lights, cameras and animation so it can move between authoring tools that don't share a native format.
Use COLLADA when a scene, not just a mesh, needs to move between two older authoring tools that both implement the schema.
Convert DAE to glTF for anything shipping to a web viewer, game engine or AR platform today, since that's the format those targets expect.
MOT to COLLADA questions people ask#
What is a MOT file?
In LightWave, a MOT file holds the keyframed motion channels for a single item: position, rotation and scale over time, saved out separately from the scene it was recorded in. Applying a MOT file to a different item in LightWave transfers that motion onto it.
Does a MOT file contain a 3D model?
No. A LightWave MOT file stores only motion channels, not geometry. It has to be applied to an existing item, whether that's an object, a light or a camera, before it means anything.
Is MOT the same format everywhere I see it?
No, the .mot extension is overloaded. This entry describes NewTek LightWave's motion file, one item's keyframe data separated from a scene; other applications use .mot for unrelated motion or audio data with a completely different structure.
What is a DAE file?
A DAE file is a COLLADA document, an XML-based interchange format created at Sony Computer Entertainment in 2004 and now maintained by the Khronos Group. It describes a full 3D scene, geometry, materials, lights, cameras and animation, so it can move between authoring tools that don't share a native format.
