Trying to run a randomizer graph on a set of floor tiles so to randomise their instance material properties.
But Dynamo complaints that the parameter is read-only and I am not being capable of running it while the Mass Editing session is open.
Any ideas, thoughts, first-person experiences on how to tackle this problem?
Sample RVT file also attached.
