Troubleshooting .MAX 3d model conversions
Morten Just, updated Mar 13, 2026Okay, so you want to convert a Max 3D model. Maybe you got your hands on the perfect model, maybe you purchased one. And maybe you thought you'd just convert it, and it'd be fine.
Update (March 2026): We shipped a completely new MAX importer that handles VRay, Corona, Multi/Sub-Object materials, compressed streams, and much more. If you haven't tried converting your file on Convert3D recently, give it another shot — it's a different experience now.
If you're still running into issues, keep reading. We can solve this together.
3ds Max files are special
Here's the deal. It's a proprietary format. Unlike USD or OBJ which are open, the Max format is pretty much a secret, and has been since it first saw the light of day all the way back in 1990. That's right, 35 years ago.
To make it worse, it's version-locked, meaning that files saved in a newer version of 3ds Max don't necessarily work in older versions. This speeds up development for Autodesk and probably also keeps the price tag down, but it's not always great for compatibility.
Finding out what to do
You don't need 3ds Max to convert a Max file. Here are your options, starting with the easiest.
Convert3D (recommended)
The fastest option if you don't have 3ds Max. Our MAX converter reads .max files directly in your browser — no installs, no uploads, no license needed. It supports VRay and Corona materials, Multi/Sub-Object setups, compressed streams from newer MAX versions, and exports to FBX, OBJ, STL, GLB, USDZ, and 70+ other formats.
Blender
There's a relatively new Blender plugin for importing 3ds Max files. It might not work for every single file, and you may have to adjust a few things, but worth a shot.
Some limitations are: animations, special shaders (like Arnold), procedural textures (will just be skipped), z-up/y-up mixed up, textures outside project folder, and so on. Most of these can be fixed by reexporting from 3ds Max. In some cases you don't need it, so your milage may vary here.

If you have 3ds Max
If you do have access to 3ds Max (or can grab the free 30-day trial or the $320 indie version), exporting directly is always an option. A few tips:
- Set System & Display Units – avoids 0.01x or 100x scale errors in FBX/OBJ/glTF exports.
- Save an Incremental Backup – keeps a clean copy before any destructive edits.
- Reset XForm & Collapse Stack – removes hidden transforms and bakes modifiers so every DCC sees the final mesh.
- Relink / Collect Textures – prevents pink-shade models caused by missing bitmaps.
- Convert Materials & Bake Procedurals – translates proprietary shaders and freezes procedural maps so they survive export.
- Test-Export One Mesh – spot problems early before batch-processing dozens of scenes.
