"Set Material" not working with "Cast to MaterialInstanceConstant"

Hey all,
I have been working alot with Datasmith/Dataprep in the last few weeks and it worked great. Recently I also started working with Materials inside custom Dataprep operations and notice a problem. When I place “Cast to MaterialInstanceConstant” in front of “Set Material” it just stops working. It doesn’t seem to matter where you put “Cast to MaterialInstanceConstant” infront of “Set Material” and in which context it is. You don’t get any warning or error.

Here is an example:

So I end up doing it in a completly different way without this kind of stuff.

Thanks anyway!
