Aura Building
by Milp
Aura Building gives Forge players on 1.20.1 a building assistant that previews shapes as translucent 3D ghost blocks before anything is placed.
What it does
Select an area, and Aura Building shows the result as real textures at 40% opacity, with a gentle pulse, before the blocks are built. The mod offers 15 build modes, among them solid and hollow shapes, walls, floors, circles, cylinders, spheres, domes and pyramids. Symmetry along the X and Z axes duplicates a build automatically, and vertical gradients run along the Y axis.
Copy and paste work from two selected points, and pasted structures appear as ghost objects positioned relative to the player. Undo and redo with Ctrl+Z and Ctrl+Y restore the full block set and return the items to the inventory. A Block Counter lists the blocks a build requires against the items in the inventory. Pixel Painter, a 2D and 3D pattern editor, works alongside it and supports depth up to 32 layers. The mod is client-side only, so it changes nothing on a server and players join without installing it. It is built for Forge 47.x and newer, and is released under the MIT License, which is not open source.
