I’m currently making a tower defense game and I am attempting to currently create a grid system. I am using blueprints to make the game. When I am working on the project and viewing the level, my RAM usage soars with the highest being around 20GB in 8 minutes. I was doing nothing when this happened, I was simply tabbed into the UE4 level view. If I tab out it stops. If I view a blueprint, it stops. If I “play” the game, it increases slightly and then seems to even out. Could this be caused by part of my blueprints or is this something with the editor?
