Make struct in Blueprint does not uses default values

When creating a struct with the “Make” node in Blueprints the created struct does not have the default values when the variable is deactivated in the “Pin Options”.


  • Create a Struct “Test” with:

“Value1” - Integer - Default Value: -1

“Value2” - Integer - Default Value: -1

  • Create a “Make Test” node
  • Deactivate “Value2” in “Pin Options”
  • You see “Value1” is set to -1 in Textedit field
  • Run the BP you will get a struct with:

Value1: -1 → perfect

Value2: 0 → wrong :frowning:

Tested with: UE 4.9.1 Launcher Version

Ugh, I think I run into this Issue right now. Whats the State of this Bug?

I have an array of Structs, each struct containing Several Integers. If I make one integer for the Struct and set array elem it seem to reset every other integer of the struct.

Since set members in struct is also bugged for arrays I wonder if there’s currently any proper way to set values for Structarrays.

Hello aWinter,

I went ahead and double checked on this issue for you. It appears as though this issues status has not yet been updated to fixed. However, I will be sure to bump up the community interest on the report. I hope that this information helps.

make it a great day
