I am unable to add a material in the Grasshopper MDL table.  
I duplicated an existing Blue Glass material and simply changed the color to Red…  
Moved the MDL to the “omniverse://localhost/Projects/TestSquare/” location.  
Added the following to the omniverseMDLtable.csv… “Red Glass,NONE,Red\_GlassC,/Projects/TestSquare,”

Unfortunately is not loading…  
What am I missing?

@rdavoliog  
Here are the instructions for Rhino  
[https://docs.omniverse.nvidia.com/con\_connect/con\_connect/rhino/materials.html](https://docs.omniverse.nvidia.com/con_connect/con_connect/rhino/materials.html)

You can use these same instructions for Grasshopper materials handling.

As there is an equivalent Documents\Omniverse\Grasshopper\omniverseMDLtable.csv file that can be edited in the same way.
