how can you mount weapons when they do not appear until runtime?

i’m swapping out an existing character and i don’t know how to pose the rifle because it’s invisible til gameplay - then, changes do not count

  1. Adjust the pose in-game.
  2. Press the small gear icon on the weapon transform component and select ‘Copy Component’.
  3. Exit play mode and paste transform by clicking again the gear icon and selecting ‘Paste Component Values’.
  4. profit
