Generating a cube floor

Hey, I am pretty new to Unreal and still trying to figure out blueprints.
But for the game I am trying to make I need a cube floor.
I cannot just place 100 cubes manually in the level, would take a while.
But I tried a blueprintscript I found on the internet.
This is what I found and tweaked.

After I tried this script, my Unreal ran into a error message!

Unreal had run into a infinite loop or if the error message would not show up it would just freeze.

So I really do not know how I could fix this or what to change.
Thx for the help and the answers.

Try the 2d Grid Execution Macro, quite handy for that kind of thing:


Do ensure you run the script someplace else than the actor that you’re spawning (Level Blueprint perhaps?); otherwise this will lead to an infinite loop as each actor tries to run the script that spawns new actors…

Thank you for the suggestion will try it out immediatly.

Update: i tested it and it worked thank you very much!
