Thats right. I’ve seen a major jump once, but that was when I was trying to move a huge terrain in the ocean project.
I should add a jump from .5 to 6 gigs… and that was my 2nd/maybe 4 times I’ve opened that project before. It could be the project too mixed with a little engine leak if is seeing it.
Edit: Just tried my project testing some UMG on the first person template and translating large amounts of objects at once say eveything in the level just once using the translate widget bumped it up from 300 → 760mb in a matter 5-10 seconds and it never settled out. Thats with no opening any BPs or anything just a clean project open and then translate all actors.
