Hello,

This seems to be working as expected from what I’m seeing, as setting an empty array to any value would cause an access violation, as it’s trying to set to a null reference. I would suggest setting up your setting in a way such as this:

You’re still trying to set to an empty array. Sprite Interfaces has nothing in it, not even an element at the 0 index. You need to add to it instead of just setting it. You’re attempting to set a null array in this case. You’ll need to initialize Sprite Interfaces in some way before setting it.
