Why convert 3DS to FBX?
The .3ds format dates from 1990 and lacks support for modern rigs, PBR shaders, and animation beyond basic keyframes. .FBX carries meshes, UV maps, materials, bone rigs, and keyframe animation in one file - which is why Unity and Unreal Engine both treat it as a primary import format. Artists migrating old 3D assets into current game pipelines need this conversion.
How to convert 3DS to FBX
Blender FREE
Go to File > Import > 3D Studio (.3ds), then File > Export > FBX; free on Windows, macOS, and Linux.
Autodesk 3ds Max PAID
Use File > Import for the .3ds, then File > Export > Autodesk (.fbx) for the best Autodesk-to-Autodesk fidelity.
Command line - assimp CLI
Run assimp export input.3ds output.fbx to batch-convert without a GUI.

- Object and material names in
.3dsare capped at around 10 characters (a DOS-era limit) and may appear truncated after conversion - rename them before exporting. - Textures are not embedded in
.3dsfiles; enable Path Mode: Copy in Blender's FBX export dialog, or place the texture files manually alongside the.fbx. - Basic keyframe animation from the
.3dsKEYF block transfers, but skeletal rigs and modifier-based animation from 3ds Max exist only in.maxfiles and cannot be recovered.
Frequently asked questions
Will animation transfer from `.3ds` to `.fbx`?
.3ds KEYF block will transfer. Skeletal and modifier-based rigs live in .max files, not .3ds, so they cannot be recovered from a .3ds source.Why are textures missing after converting?
.3ds stores only texture file names, not image data. You need the original texture files alongside the .fbx, or use Blender's Path Mode: Copy option to embed them during export.Which FBX version should I use?
Does converting lose geometry quality?
.3ds assets often have flipped normals or non-manifold faces - fix these in Blender before exporting to avoid artifacts in Unity or Unreal.
