World Partition + Datalayer on child actors

Development World Creation
1

I am new to World Partitioning and don’t understand how datalayers are supposed to work at runtime:

Let’s say we have a Static Mesh Actor “Car”.
The car is on a datalayer, also named “Car”.
Attached to the car as a childactor we have a static mesh actor “Driver”.
The driver is on a datalayer named “Driver”.

I want to hide the driver by setting its datalayer to Loaded (or Unloaded).
This simple task does not work for me in runtime:
As the game starts the drivers datalayer gets replaced by the cars datalayer and therefore it’s not found:

In general, child actors get driven by their parents, in other words they lose their data layers and inherit their parents datalayers.

Why is this and how can I reach child actors at runtime using datalayers?

Hi @Cascho75,

is it important for you to put the driver out of memory, or just make the driver visible/invisble?

Because for visibility you can use the object manipulator device easy.

Thank you very much for your answer.
I already use “SetVisibility”-Node but in this case I indeed want to remove the actors from memory and also I want to understand and make use of the DataLayer stuff.

I have also noticed that the data layers do not work as soon as they are attached to another mesh or actor…

you would have to leave the driver seperatet in the hierarchy, but then you would have the problem that he does not drive directly with the car, but would have to organize his movement simultaneously…
