I really don’t understand, over a year now and cannot get this working!

I’m even using Revit and the AdvancedGlassPack materials which is exactly what this script is using

It’s using the exact smae same names even, yet the python script does not work.

I don’t understand why it’s so easy for everyone

I don’t know about python and I struggled with the same error

but I solve it. It means that can’t change Material and Material Instance. Same Class(eg. Material to Material) is possible.

Try it
