My game have Lobby scene (bunch of 2d UIs), Adventure mode (3d hexagon field), Battle mode (3d field). In this case, what is good for performance? (targeting for Nintendo switch, middle~high mobile device) 1. Divide scene? 2. Load them all in one scene and just turn on/off (activate mother gameobject) when needed. 3. Instantiate needed mother gameobject that contains all needed child gameobjects for one scene (adventure, battle) and destroy it when finishes. 4. other way? Thanks.
