I’m developing a game that requires sub-levels and physics bodies as props and objects. The game has sandbox features - player can carry and move objects around.
While keeping them on the persistent level, they falls due there are no collision data from unloaded levels. Placing them on each sub-level is not an option: they disappear and reset when player moves to another sub-level plus the game needs to keep those actors always loaded due gameplay features. I’d like to know the approaches to keep the physics bodies loaded and prevent them from falling / simulate physics when the current sub-level they are in unloads.
