Try:

If inputMesh Is Nothing Then

do stuff

End If

Actually in this case it would be if inputMesh is Not Nothing, but even then I get:

1. Error (BC30020): 'Is' operator does not accept operands of type 'Integer'. Operands must be reference or nullable types. (line 120)

My forehead has permanent palm prints in it.  Might as well be a tattoo :)

I was explicitly trying to look for Null items a long ago by using the IsDBNull(item) Boolean, but with no luck. Again in this case it doesn't work cause I am missing something.

Private Sub RunScript(ByVal x As Mesh)
If IsDBNull(x) = False Then
print("what")
End If
End Sub

Any insights on that?
