How to Save and Load a Massive Build with Huge Structure Blocks

Capturing the Structure

Place a Structure Block and set it to Save mode. In the size fields, enter the dimensions of your build. With this mod installed you are no longer capped at the vanilla limit, so you can push the X, Y, and Z sizes far beyond what the base game allows. Watch the bounding box outline as you adjust the numbers — it now renders from much farther away, so you can still see the corners even when you are standing well back from a huge build.

Use Detect mode if you want the block to auto-fill the size fields by scanning for connected blocks, which saves you from counting manually on irregular shapes.

Loading It Back

Switch the block to Load mode and enter the same name you saved under. Set the offset so the structure lands where you want it, then press Load. Because the mod raises the size ceiling, a single Load operation can place a build that would have been impossible to store in vanilla. If a load seems to fail, double-check that your size fields still match the saved dimensions — a mismatch is the most common cause.
