About Dimension Stages mod
In fact, the mod is a utility for the GameStage API. In the game Minecraft, players must unlock levels over time. The more they play, the more levels they can unlock. However, how you unlock them depends on the server or modpack.
Apparently, after installing this mod, you can restrict access to a dimension. You do it through CraftTweaker. This is the script method you use to attach the dimensioning stage.
You cannot import dimensions with a constraint. If you have the stage, you can do it. Entities owned by the player will also be checked by the mod. This prevents owners from joining dimensions if they don’t have a stage. This is really a mod worth experiencing in the future.
Dimension Stages mod will be installed through Minecraft Forge.
