Unity Addressables: Content Organization
By Unity Technologies
Organize Unity content with Addressables groups, addresses and explicit asset lifetimes.

Use it for: Optional scenes or content packs loaded when needed.
Start: 1) Match the package version. 2) Assign one prefab an address and group. 3) Load and release it, then make a target-platform content build.

Try checking: Re-enter the scene in a player build and inspect dependency and memory behavior.
Limits: Groups affect bundle packaging; labels help select assets. Remote content needs hosting and correct paths. Automatic dependency loading does not remove your responsibility to release assets.
