Problem with Material Function

Development Rendering

hey guys,
I have a little problem with material functions, i’m in the progress of rebuilding an material from a markplace demo.
Everything is woring fine expect one little issue, please check the screenshots.
I just don’t get why the material editor “in my level” is asking for a missing function input? the same construction is working fine in the marktplace demo…

I just found the issue… in the material function “metal” i had to check the “Uese prewiev value as default” in the function input node…

I’ve been having the same problem with pretty much any material I import from Quixel with 5.4. Pretty much every material shows “[SM6] Missing Material Function”, sometimes the fix is easy and it’s just a node that’s disconnected in a function.
