uhh/// OR you (in 3D Package) could:
- create dummy obj at world center, (0, 0, 0)
- Then select all objects,(wherever they are in the 3D scene), and without moving the objects, Align just there Pivots (all at once), to the center dummy.
- Then whether you import multiple FBX’s into Unreal all at once, in a big file, or even one at a time, everything will stay/go exactly where it is supposed to in Unreal.
ALSO: (I will test this later) BUT I suspect if you do this procedure above, you can perhaps fix the pivots with below:
- back in 3D package UNDO your ‘center every pivot’ command (or reload your scene)
- Then export and save OVER the previous FBX.
- In Unreal right click objects (or groups? multi-selection?) and select: "Re-import’.
I kinda feel objects will re-import the model, where they already are in 3D space in Unreal BUT with centered pivot, because it’s like a ‘change’ ?? I have to go try this now 
LOL!
Either way, the first part is a way to have all non animated objects, pros, sets and scenery, come easily into Unreal IN PLACE / IN SITU… Easy enough to place the few animated objects or things that rely heavily on Pivots being Centered or whatever,…
I can’t get any help here doing a simple BOUNCE in my VR game, after asking for 7 months. So I am having to SHELF my 95% finished Zero-G VR game that puts ‘Lame Echo’ to SHAME,.
PLEASE NOTE: I am still willing to help others even if I have never GOTTEN ANY HELP, MY POSTS AND QUESTIONS REMAIN UNRESOLVED.
If what I have said above all works, it is a GAME CHANGER procedure. So, If you know Blueprints well and know how to tell Unreal to simply BOUNCE IN THE CORRECT DIRECTION (that is all I need,) THEN PLEASE HELP ME BACK! RESCUE MY GAME!
