How to build a giant Sculk Catalyst in Minecraft
The Sculk Catalyst block, 16 times bigger: every pixel of its real texture becomes one block. Plan it, gather the exact blocks and build it layer by layer.
- 16 × 16 × 16 blocks (wide × tall × long)
- 1,352 blocks hollow (21 stacks + 8), 4,096 solid
- 16 layers from the bottom up
- 11 kinds of block
Blocks you need
For the hollow build at real size, with 1-block walls. In the builder you can pick other block groups, a different size (½× up to 16×) or a solid build, and the list changes with it.
| Block | Count |
|---|---|
| Black Concrete | 511 (7 stacks + 63) |
| Light Gray Wool | 167 (2 stacks + 39) |
| Stone | 149 (2 stacks + 21) |
| Sculk | 138 (2 stacks + 10) |
| Smooth Sandstone | 138 (2 stacks + 10) |
| Cyan Terracotta | 135 (2 stacks + 7) |
| Stripped Birch Wood | 56 |
| Gray Concrete | 39 |
| Light Blue Wool | 11 |
| Cyan Wool | 7 |
| Cyan Concrete | 1 |
How to build it
- Plan: choose the blocks you have, the size, hollow or solid, and the build direction.
- Gather: get the exact block list in stacks and shulker boxes, or download it as a Litematica schematic.
- Build: place one layer at a time, with a 3D view and a 2D map of each layer that counts the blocks in every row.
