Here’s the setup and what’s not working.
Here’s the composed GameFeatureData:
This is the sub_level.
The cube is not spatially loaded while the sphere is. Streaming is enabled in the sub_level.
This is the main_level when it loads in the editor. As one can see, the sub_level is loaded, but only the cube actor is there, which is expected as the sphere actor is not yet spatially loaded.
Until this point everything is fine and expected.
If we go to the world partition settings and load the region where the sphere actor would usually be, nothing will happen at all. The sphere actor from the sub-level will not be loaded into the editor scene.
The region is loaded, but it does not load the spatially loaded actors from GameFeatureData composed sub-levels.
However in-game it just works as expected, the sphere actor will be spatially loaded just fine. It only affects the editor flow.
Why is that?
