Nice function, thank you for that.
I tried adding the “IsValid” node (the macro with Execs, not the function). I tried “IsValid”, “Is Valid” (both with quotes), IsValid (without quotes), the whole path (/Class/…), even “StandardMacros:IsValid”. Some of them resulted in the IsValid function call (the one with the boolean output), none of them spawned the IsValid node I want.
Can someone help?
