Universal Material Converter

3 votes
Date Updated: 

This Universal Material Converter is an enhanced version of the old AMC script. It convert materials between renderengines. It converts from Autodesk Materials and also converts textures as much as possible when needed.
Currently supported renderengines are: MentalRay, V-Ray, iRay, Corona, Scanline, FStorm, ART, Arnold, Octane, Redshift (beta)
Coming up: Maxwellrender (maybe)

You will need at least have a demo version of the renderengines installed if you want to be able to support conversions.

While for example converting a V-Ray material to Corona, it will also convert bitmaps to Corona-bitmaps and VRayDirtmap to CoronaAO.

This script is available from our webshop: https://3dstudio.nl/hikashop-menu-for-brands-listing/product/universal-m...
It comes with an .mzp installer, automatic renderengine check, check on duplicate materials (to make them instances). And the option to bake procedural textures to bitmaps when converting to Standard material, so you can export to several VR engines.

We have 2 videos on youtube to explain installation and usage

-- added 2018-07-10
version 1.6.2 is available, with support for OSL textures, Max2019, V-Ray NEXT, Corona v2 and it now will also check for duplicate materials that are nested.
A new feature is the option to load your own matlib file to get source materials from. (during conversion, it will check the matlib for a material with the same name and use that to replace instead of convert)

-- added 2019-12-16
version 1.8 is available. With support for Max2020, latest versions of all supported renderers. Support for FStormrenderer, basic support for RedShift, and support for conversions from Octane. Also new is the User Interface, the option to save/load your conversion preset and a VR mode for conversion to V-Ray, to bake procedurals and colorcorrections for export to Unreal (through V-Ray)

-- added 2020-07-01
version 1.95: V-Ray 5, Octane 2020.x and 3dsMax2021 support. Development for mentalray and iray conversion has stopped.

Hi, i have a .c4d file with octane render materials, i need to convert the materials to vray for 3ds max, is this possible with UMC? how? Does UMC only install on 3dstudiomax? Can i convert materials using cinema4d+UMC or do i have to convert the file from .c4d to .max and then convert the materials from sdstudio+UMC?

Hi. for updates, please contact me or watch your email. We will send out update emails when we release a new version. Everyone who bought the script should be on the mailinglist and will receive it automatically.
