Spawn Dimension

The mod adds an option to select your starting spawn dimension when you create a world

You can select your starting dimension when creating a world. It supports vanilla dimensions—Overworld, Nether, End—as well as dimensions added by other mods, like the Twilight Forest.

If you don't make a selection,  your starting dimension will default to the Overworld.

When you select a dimension other than the Overworld as your starting dimension, the mod will clear the blocks around your spawn point and generate an obsidian platform right under your feet.

You can totally use this mod alongside other mods. Such as: Starter Kit
