I tried posting about this earlier in the AnswerHub but didn’t get any replies (not sure how often people are actually checking it). As far as I can tell, there doesn’t seem to be any way to correctly scale a Blueprint or Group of several actors together as an actual contained group. Instead everything just takes the master scale being manipulated (say the X axis for example) and then applies that axis scale value to all the other grouped actors on their own local scales.
From an efficient world building perspective, this is a pretty big problem as it means I can’t go and create a nice arrangement of actors, put them into either a group (for a single level) or a Blueprint (for easy access from the content browser) and then mirror or otherwise adjust the scale of that grouping. For ease of explanation, I made a little gif below.
Also beyond that, is there any better way to simply group an arrangement of actors together in the content browser for easy reuse later other than to create a whole new Blueprint for them? It seems like allowing simple Groups in the content browser that exist purely as lists of actors and their arranged positions/rotations/scales would be beneficial, especially since it means several scripted Blueprint actors could be grouped together and accessible as a single searchable entity in the content browser.
