Create: Building Dimension
by GracelessDev
Create: Building Dimension gives players a creative-mode dimension reached through an Amethyst portal, where contraptions can be tested before they go into a survival world.
What it does
Building a hollow rectangle of Amethyst Block at least 2 wide and 3 tall, then lighting it with Flint and Steel, opens a portal. Walking through it starts a short timer, after which the player is moved to a dedicated creative dimension. Stepping back through the portal returns the player to the exact spot they left, with their original inventory, game mode and position.
Each visit is separate from survival play. The survival inventory, including Curios accessories, is stored when the player enters and restored on the way out, while the creative dimension keeps its own inventory. Anything built inside stays there, so nothing crosses back into the survival world. Tools, blocks and Curios accessories set up during one session reappear the next time the player enters.
The mod is built for testing Create and Create Aeronautics contraptions, including ships and flying builds from Sable, before they are attempted in survival. The server and every player need the mod installed. Files are published for NeoForge 1.21.1 only.
