I have three data layers intending to represent three different seasons and I’m having trouble adding the procedural foliage actors to different data layers. Is there any way to do this?
Edit: I selected the Instanced Foliage Actor instead of the procedural foliage volume and was able to add it to the data layer
Well,You can use Actor Foliage.
in 5.3 the details pane seems to be blank when you click on a foliage actor if it is part of an instancedFoliageActor. Making them impossible to move between data layers.
Also the InstancedFoliageActor’s DataLayers pane is grayed out and unmodifiable.
I’ve noticed this as well. Found any fixes or workarounds?? 
Why i can’t add Actor Foliage in foliage mode, it only support static mesh foliage type
The plus sign next to the search bar will let you add the actors to a data layer even though it is grayed out.Same with landscape proxies. Seems like a bug. I will note though that even though its goes in there, it wont load and unload the foliage actors in game for some reasons. The landscape works though. For the foliage, I ended up having to set it as hidden and remove the collision from my foliage at all times as a work around. Not ideal.
Lads,
You’re adding your foliage to the persistent level “CORE” “MAIN” level.
you have to select the data layer - “double click” then ADD the foliage to that layer. The Sub layer.
hi~ i wonder u found a way to solve this issue or not.
in my case make a sub data layer and double click . and change foliage mode and clicked ‘Move’ button in foliage mode. then i can move selected foliage to the data layer i chosen. i hope it can help u
