Procedural Foliage Landscape Layer Spawning Not Working With Landscape Streaming Proxys?

Hey all,

I have ran into an issue with Procedural foliage spawning. I have set up the foliage types to spawn on only certain landscape layers however it refuses to spawn anything at all. It appears to be because we have the map split up into streaming proxy’s? I tested the same set up on a simple landscape and it works fine. Am I missing somthing?
