userCustomEPLibrary not accessed by CallFromEPContrLibrary in Rhino 6

I copy pasted the EnergyPlus material data set into userCustomEPLibrary to use the material codes to easily pick them by CallFromEPContrLibrary.

It was working fine in Rhino 5. But in Rhino 6, CallFromEPContrLibrary does not access that library. Does anybody have an experience on this?

I could solve the problem.
Apparently for Rhino 6, the user custom library must be in the same folder as the GH file (and not in C:\Users\XXX\AppData\Roaming\Grasshopper\Libraries, as was the case when I was working with Rhino 5).

I don’t believe the reason of not taking the custom library is what you said.
I use R6 and custom library in the exact same functionality as in R5.
Check the output of your LB_LB and HB_HB to see where the default folder is set. Maybe instead the path you mentioned it is C:\ladybug … or other?
