Set material parameter value <By Category>

Hi @acXBWH8 …not sure if this could help…

Set a Key Schedule Parameter back to (none)

Hmmmm… try using an invalid element? (Select by ID, -1 as the ID, feed that). Might not work though. This may require a more direct Revit API interaction (IE: Python, or a custom zero touch node) to ensure the right override.
