Five apps
The same license opens .max files in SketchUp, Cinema 4D, Blender, Maya and Houdini, each with its own renderers. It also opens them in 3ds Max, if you have it.
Cinema 4D · Redshift · Corona · V-Ray · Octane · Arnold
Open .max files in Cinema 4D. Rebuilt for your renderer.
Most archviz models are .max files with Corona or V-Ray materials. Oruva reads the 3ds Max scene itself and opens it in Cinema 4D as a native scene, with editable materials for the renderer you use.

How it works
From .max to Cinema 4D. No export step.
- 01
Add your folder
Point Oruva at the folder that holds your .max files and their preview pictures. It connects each picture to its model.
- 02
Send to Cinema 4D
Right-click the picture, choose Send to, Cinema 4D, then Redshift, Corona, V-Ray, Octane or Arnold. Missing textures are listed before sending.
- 03
Edit natively
A native .c4d scene opens with real, editable node materials. Anything approximated is listed in a report.
98.5%
of 335 .max files picked at random from a real 73,871-file model library converted in our October 2026 test. Anything approximated is listed in the conversion report.
What comes across
- Files saved in 3ds Max 2009 through 2027
- Native Cinema 4D geometry, object names and hierarchy
- Materials rebuilt as editable nodes for Redshift, Corona, V-Ray, Octane or Arnold
- TurboSmooth arrives as native subdivision; MeshSmooth, Shell, Edit Poly, UVW Map, Bend and Twist are applied
- Textures found by filename next to the .max, in nearby maps folders, or in a folder you add once
- Renderable splines, including Sweep
- V-Ray proxies, as regular geometry when the proxy file comes with the model
Good to know
- Cinema 4D 2024 or later on Windows today. Oruva for Mac is coming.
- Forest Pack, RailClone and Corona proxies aren’t supported yet.
- Symmetry, Mirror, Chamfer and some other modifiers aren’t applied. Oruva uses the base mesh and warns you.
- Renders won’t always match 1:1. When a renderer can’t express something exactly, the report says so.
One license
More than a converter. Your whole library.
A library that finds things
Local AI tags and describes every preview, so you can search by words, colour or a photo. It runs on your computer.
Scenes built by ChatGPT or Claude
Give your assistant a photo or a sentence and it builds the scene with the models you own. Included with a paid license, on Windows.

Questions
Before you download
Do I need 3ds Max installed?
No. Oruva reads .max files on its own.
Which 3ds Max versions can it open?
Files saved in 3ds Max 2009 through 2027, including the older versions most model libraries still use.
Which renderers?
Redshift, Corona, V-Ray, Octane and Arnold, whichever are installed in your Cinema 4D. Oruva only offers the ones your Cinema 4D can load.
Will the render match exactly?
Supported materials become native, connected nodes. When a renderer can’t express something exactly, Oruva reports the approximation instead of hiding it.
Are my files uploaded anywhere?
No. Conversion runs on your computer. Your account is used for the license check only.
Does it work on a Mac?
Not yet. Oruva for Mac is coming.
What does it cost?
$99 once at the launch price, until 22 March 2027, then $149. It includes one year of updates, for one person on up to two computers. No subscription.
