About Autodesk FBX
Common Use Cases
- Importing legacy 3DS models into Unity and Unreal Engine
- Upgrading 3D Studio files for modern Autodesk tools
- Preparing 3DS assets for game development pipelines
3DS is a legacy format with strict limitations, including a 65,536 vertex cap per mesh and minimal material support. FBX is the industry standard interchange format for game engines, film pipelines, and modern 3D software. Converting from 3DS to FBX unlocks your legacy assets for Unity, Unreal Engine, Maya, Blender, and the full Autodesk ecosystem.
3DS is limited to basic meshes, simple materials, and 65K vertices per object. FBX supports skeletal animation, blend shapes, PBR materials, cameras, lights, and complex scene hierarchies with no vertex limits.
Why Convert 3DS to FBX?
Import into Unity and Unreal Engine
Both Unity and Unreal have first-class FBX importers. Convert your 3DS files and drag them directly into your game project.
Access modern material features
FBX supports PBR materials, multiple UV channels, and complex shader properties that the 3DS format cannot represent.
Remove the vertex limit
The 3DS 65,536 vertex cap is a format limitation. FBX has no such restriction, so high-poly models convert without truncation.
Stay in the Autodesk ecosystem
FBX is Autodesk native. Converting from 3DS to FBX keeps your assets compatible with Maya, 3ds Max, MotionBuilder, and Mudbox.

How to use
- Upload your 3DS file. Drag and drop a .3ds file onto the upload area, or click to browse. Files up to 500 MB are supported.
- Start the conversion. Click Convert File. 3DS geometry and materials are converted to FBX format compatible with modern 3D tools.
- Download your FBX. Save the .fbx file and import it into Unity, Unreal Engine, Maya, or any FBX-compatible application. Files are deleted from our servers within 1 hour.
Frequently asked questions
- Are materials preserved?
- Basic diffuse, specular, and opacity material properties are converted. Advanced PBR materials are not available in 3DS and will need to be set up in your target application.
- Does it handle multiple objects?
- Yes. All mesh objects in the 3DS file are preserved as separate nodes in the FBX scene hierarchy.
- Can Unity and Unreal import the output?
- Yes. Both engines have native FBX importers that handle the output directly.
- Are animations converted?
- Basic 3DS keyframe animations are converted where present. The 3DS format has limited animation capabilities compared to FBX.
- What about textures?
- Texture file references are preserved in the FBX. Make sure texture files are available at the referenced paths when importing into your 3D application.
- Is converting 3DS to FBX free?
- Yes. Free with no signup. Anonymous users get a daily allowance, registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
- What is the file size limit?
- The maximum file size is 500 MB per conversion.
