Pick anything you want to craft and see exactly which raw materials you need — with stack counts, a live missing-materials list, and the full crafting tree, for both Java and Bedrock Edition.
Loading crafting calculator…
The calculator walks the full crafting tree for every item you add — recipes, smithing, stonecutting and smelting — and aggregates ingredient demand across shared materials, so a build that needs sticks in three different places only counts them once.
No. The totals show what you need to smelt (ores into ingots, sand into glass, and so on) but not the coal, wood or other fuel that powers the furnace itself.
It stops the breakdown at ingots, glass and other smelted products instead of continuing further back to raw ore or sand. Turn it off to see the fully raw shopping list — every log and ore block you need to gather.
Their contents (water, lava, milk, honey) aren't modeled as craftable resources, so the calculator treats the filled container itself as something you need to have on hand.
Yes. Paste the contents of a Litematica materials.txt export into the import box and the calculator adds each item to your project, prefilling how many you already have from the Available column.
