thanks! here’s how I managed to mass-collapse every sub-folder (in U4.25):
with the parent folder in a collapsed state, SHIFT-click on the parent folder’s little triangle to expand it with all sub-folders expanded and then again SHIFT-click to collapse it again;
CTRL-click on the parent folder’s little triangle to open it with all sub-folders collapsed
What’s interesting is CTRL-click will only work if the parent folder has been previously closed with SHIFT-click…not really sure why this is.
Epic can push out Nanite, Lumen and lord knows how many other huge technological achievements yet saving the collapsed/uncollapsed state of folders is still a no-go. The amount of development time wasted because of this simple broken feature…
