Spout receiver to Render Target?

Is it possible to use a Spout receiver to write to a Render Target? I’ve tried using the Mat output to a Draw to Render Target Node directly, as well creating a MID on a plane, writing the tex to it, using Get Material then Draw to Render Target. Both the Mat and Tex on the MID display on the planes, but they won’t Draw on the Render Target at runtime:

Not sure what’s going on, appreciate any help. Thx!
