Blueprint function struct array variables lose their defaults

Hi,

I just ran into a little showstopper:

I declared a function in a BP function library that use an array filled with some constants to do its thing.
This array is declared as a local variable inside the function.
I fill the array with the data and use the function in my actor blueprints.
So far, so good. -Until I restart the editor. The array in the function now lost all its entries, thus things go south.

It would be great if variables in function declaration would retain their defaults over editor restarts.

Repro steps:

  1. Create a BP function library

  2. Create a function within the library

  3. Create a struct with some members of some type

  4. Add a local variable of the struct type to the function

  5. Make the variable an array

  6. Add a couple of entries to the array

  7. Save everything

  8. Close and restart the editor

  9. Observe that the array now only has 1 item, populated with the arry type’s default values

Thanks for looking into this :slight_smile:

Cheers,
Klaus
