Read the material list
Every build page counts materials from the same coordinate model that drives the 3D view, layers and exports.
The numbers are generated, not estimated: if the model contains 589 cells, the checklist accounts for all of them.
How the counts work
- Doors and beds: one item per complete pair, not one per cell.
- Double slabs: two items, because each consumes two slabs.
- Water: excluded from the checklist; two water buckets are listed separately when a farm needs them.
- Stack size: 64 for most blocks, 16 for items such as eggs or signs, 1 for unstackable blocks.
From list to supply run
Round up to full stacks and add a small buffer for mistakes, especially on diagonal roofs and curved walls.
Bring scaffolding or dirt for reach, and empty shulker boxes if the build needs more than an inventory.
If something does not work
Why is the item count lower than the block count?
Doors and beds are two cells but one inventory item per complete pair, so a 589-cell cabin can need 587 items.
Are shulker boxes included?
No. The list covers the blocks in the build, not the containers or tools you bring.
Can I export the checklist?
Yes. Open the Materials tab on a build page and use Export checklist .txt; the prepared checkboxes are saved in this browser.
