Accessing rhino materials within grasshopper

hello all.
i am wondering how is oit possible to access and assign a material from rhino material library ( C:\Users*USER*\AppData\Roaming\McNeel\Rhinoceros\6.0\Localization\en-US\Render Content )

the idea would be than to be able to upload the material and use it without the whole process i described in the image. this could be sweet.

would love the help, or where to find some C# direction to start getting into it.
cheers y’all

Seems like it works out as you did it.

no do it without a ref rhino geo. thats the whole point. i want to have clean rhino. this library should be accessible without creating a shape, assigning a rhino mat > uploading it to grasshopper… exploding the attributes to finally attach to a preview component.
too long to do it each time

Got it… But in that case, even if you don’t want to create geometries in Rhino scene, at least the materials you need in your Rhino Document should be loaded first.

the question is how to access the rhino material content table … human is not the key
i wish to not load material manually to rhino. i want a Gh access directly to the folder. couldn’t find any way to upload the files so far

Hello
you didn’t try too much. Just think that David Rutten has already solved this :innocent:
So just put the name of the material file, it works for me.


If you want the list of material, it mus be doable but it will give you a long list

i didnt know that, Thanx Laurent!!!

No problem, as David said there are lot of Easter Egg in Grasshopper. So there are many functionality that are not known, documented …
I use something like that to copy the full file name of a file

In windows if you shift+right click a file it gives an option to ‘copy as path’.

Does the error occur because of material input or geometry input ?
Test the custom preview with simples inputs to track the cause of the error.

Custom preview works with simple inputs as colors.
The error message is appearing when I’m trying to use a material from library, exactly like in your example
Thanks

Hi,
There is any conclusion?
Thank you!
