3ds Max 3D file formats: what opens and how
Autodesk 3ds Max is a modelling and rendering package popular in architecture, product visualisation and game art. It opens 3 of the 9 common 3D formats below without conversion; for the rest, convert to OBJ first.
Format support at a glance
| Format | Support | How |
|---|---|---|
| GLB | Convert first | Convert to OBJ |
| glTF | Convert first | Convert to OBJ |
| OBJ | Built in | File › Import › Import…, file type OBJ |
| STL | Built in | File › Import › Import…, file type StereoLitho (*.stl) |
| FBX | Built in | File › Import › Import…, file type FBX |
| PLY | Convert first | Convert to OBJ |
| 3MF | Convert first | Convert to OBJ |
| DAE | Convert first | Convert to OBJ |
| USDZ | Convert first | Convert to OBJ |
Which format to choose
FBX and OBJ are the most dependable choice for 3ds Max. Geometry, materials, cameras, lights and animation come through the FBX importer. If a model arrives as GLB, glTF, PLY, convert it to OBJ so materials survive the trip.
Units and orientation
3ds Max works in set per scene in Customize › Units Setup and is Z-up. Most problems after an import, such as a model that is invisible, enormous or lying on its side, come from a mismatch with the exporting app rather than a broken file.
- Match System Unit Scale in Customize › Units Setup to the file's units before importing to avoid scale surprises.
- Use Reset XForm on imported objects before modifying them, so their transforms are clean.
