Place Blocks Next to Structure Voids Without Replacing Them

The Problem

When building with Structure Void blocks, clicking on them normally replaces them instead of placing a block adjacent to them. This makes precise construction frustrating.

Solution: Use Block Placement Mode

Press Page Up to enable placement mode. This toggles your interaction so that clicking on invisible blocks (Structure Void, Light, or Barrier) will place blocks *next to* them instead of replacing them.

How to Use

1. Hold the block you want to place in your hotbar

2. Press Page Up to activate placement mode

3. Look at the Structure Void block where you want to build

4. Click to place your block adjacent to it

5. Press Page Up again to return to normal mode when finished

This mode stays active until you toggle it off, so you can place multiple blocks in succession without re-pressing the key. It works with all three invisible block types, making it essential for detailed structure building around these blocks.
