The eight slots
When you add a piece you pick a slot. The slot decides where it's worn, what shape it is, and how big your drawing area is.

| # | Slot | Worn by | What you're painting | Canvas |
|---|---|---|---|---|
| 1 | Helmet | Players | The head, plus the slightly larger “hat” shell over it | 64×32 |
| 2 | Chestplate | Players | The torso and both arms, full length | 64×32 |
| 3 | Leggings | Players | The whole leg, from feet to neck | 64×32 |
| 4 | Boots | Players | The entire leg — not just the foot | 64×32 |
| 5 | Elytra | Players | The back face of the wings | 64×32 |
| 6 | Wolf armor | Wolves | The wolf's body | 64×32 |
| 7 | Horse armor | Horses | The horse's body | 64×64 |
| 8 | Harness | Happy ghasts | The harness. Goggles flip down when ridden. | 128×128 |
The most important thing to understand: you are painting, not modelling. Minecraft fixes the shape of every armour piece — you cannot add horns, spikes or capes. What you can do is repaint every surface of that shape, which is enough to make gear look completely different.
Things that will surprise you
- Boots paint the whole leg. Only the bottom shows in game, but the canvas gives you the full leg. Paint the foot area.
- Chestplate includes the arms. Don't forget the sleeves — they're a separate part of the canvas from the torso.
- Helmet has two layers. The head itself and a slightly bigger shell around it. Use the outer shell for bulk and trim.
- Wolf and horse armour get vanilla damage cracks drawn on top by the game. You can't turn that off.
- Foals never show horse armour. That's vanilla behaviour.
- Harness needs Minecraft 1.21.6 or newer. Its card carries a
1.21.6+badge.
Which vanilla item is it based on?
Every piece is built on a real Minecraft item — an iron chestplate, a diamond horse armour, and so on. You pick which on the Stats tab under Base Material (Vanilla Item). See Stats tab.
