Autodesk Physical Materials Locked?

[El8ias]

From the Physical Materials menu, I double click on a material used in the file getting the Material Editor then click on the Asset Browser to open the Asset Browser's Autodesk Material Library. The issue is next to each option is a "Lock" Icon. I would like to acces the Autodesk library for my models , is there a way to unlock those files?

Hi Eli,

They are read-only libraries and cannot be modified directly.

We may use “Replace in Editor” and then adjust the value. A new material will be generated in the current model. If we want the material to be used in other models, we can add the new material to Favorites library which can be accessed in other models.

I am also trying to pull from the Assets Library. I see the option to Add to Editor, but it is greyed out and pointing at it does not cause it to be highlighted.
