Save/Import *.rmtl files via Scripting/Command

Is there currently a way to use RhinoScript or any command to export Rhino materials as rmtl files?
I can only do it now manually from MaterialEditor and would like to be able to automate it.

Hi Jarek, you can try to script below commands, they do not autocomplete:


note that you`ll need to define the material name and loading does not assign.



Hi Clement,

Thank you very much, that is exactly what I was after and will get the job done! Much appreciated.

On the side note - I wonder why this is not documented in Help or will not autocomplete… the only source online I could find a mention about it (and a bunch of other Render… commands) is here:

Bunch of useful stuff for macros/scripting of render/materials/textures:

I guess we have to ask @andy why some the RDK commands do not autocomplete ? There are some test commands as well which i guess are used internally. I´ve written some of the working commands down into a text file when had downloaded the plugin for Rhino4 long time ago. In Rhino5 the RDK plugin seems to be included by default.


I can’t for the life of me remember why. I suspect it may have had something to do with documentation.
