Serialization, save game - Stride Forums Archive

As far as i can see the engine is also deferred, meaning you have the whole scene serialized (like unity)
unity however lacks saving mechanism because scripts are constructed through ECS factory, which is hidden in the cpp part of the engine.
I wonder what mechanism for saving the game Xenko provides?

i wonder too
currently it looks like it has to be done manually
