I have a blueprint only project and one of the blueprints is very large and when I have it open the RAM usage increases every time I hit play. RAM usage does not increase when I don’t have that particular blueprint open when I hit play.
I have 16GB RAM and it starts to fill up and working with the project gets slower and slower to where I have to close the project and re-open it. The amount of RAM each play adds to the usage increases each time also. I can close that particular blueprint and some RAM will free up. The large blueprint is the game mode so maybe that is part of the problem. The size of the blueprint is 6.6MB and I’m using 4.6
edit: I just realized I probably should have put this under bug reports.
