How to Generate Pixel Art That's Actually Usable

AI draws a sprite in seconds. Getting the sprite you need takes a few habits. Here they are, with real results. Every image below came straight out of PixelZ, not touched up.

Where to generate

• AI tab in the editor: draws onto your canvas with PixelZ Core v1. Use it when you want to keep working on the sprite by hand. Drag Select area [J] to generate into one part of the canvas only.
• Generate page: more models and sizes. Results go to your asset library.

The AI tab has three modes:

• Create draws from a prompt.
• Edit changes a layer you already drew.
• Style draws a new object in the style of a reference sprite.

What you can make

A game's worth of assets, one prompt each. The label is the Type I picked.

Character

small goblin merchant holding a coin bag

Creature

small green slime monster

Item

health potion in a round glass bottle

Item

steel sword with a blue gem in the hilt

Effect

blue magic fireball

UI

wooden fantasy inventory frame

Tile

grass with small stones

Background

night forest with a full moon

1. Pick the Type first

Type tells the model what you're drawing: character, item, tile, background… It decides what you get back:

Type: Item

red mushroom

Type: Tile

grass with small stones

Type: Background

night forest with a full moon

• Default guesses from your prompt. grass tile gives a tile. castle background gives a background. Anything else gives a sprite with no background.
• Want the full body? Pick Character. Just the head? Pick Portrait.
• Tile is for ground and walls: grass, stone, water. Not for objects.
• Picked a Type? Don't write it in the prompt too.

2. Write the prompt in four parts

• Subject: what it is. a knight
• View: the camera angle. side view alone is often not enough. Name the kind of game: side-scroller platformer sprite
• Style: only what the Type doesn't cover. dark fantasy, warm colors
• Details: one or two. glowing sword, red cape

One word

knight

Four parts

3. One subject per prompt

The most common mistake is putting a whole scene into one prompt. You get a picture, not a sprite you can use in a game.

a knight fighting a dragon in front of a castle with a treasure chest, trees and a river

Need a dragon and a castle too? Generate them separately.

4. Fix it with Edit, don't re-generate

Result close but not right? Don't generate again: you'd get a different knight. Switch to Edit and change one thing. The rest of the sprite stays.

Start

the generated knight

Edit

make the cape blue

Edit

replace the sword with a battle axe

5. Generate ×4, pick the best

Set Variants to ×4. One prompt, four different results. Pick the best one and fix it by hand. That's faster than generating one at a time until you get lucky.

Every result lands as a normal layer. Stray pixels? Fix them with Pencil [B].

6. Use a reference to keep a set consistent

Generate items one by one and each looks like a different artist drew it. The fix: make the first one, then use it as a reference for the rest. It works best when the reference has a strong look of its own.

obsidian sword with glowing orange lava cracks

kite shield

knight helmet

Reference

In the editor, use Style mode. On the Generate page, add the sprite as a reference image. A rough sketch or a photo works too. It guides shape and colors better than words.

What to avoid

• Contradictions: tiny detailed epic huge
• Lists of objects: one subject per generation.
• Negative instructions: no blur. Say what you want, not what you don't.

From generation to game-ready

1. 1

   Type first, then prompt

   Pick the Type, write the four-part prompt, set Variants to ×4.

2. 2

   Pick and clean up

   The best variant is a normal layer. Fix stray pixels with Pencil [B] and match the colors to your palette.

3. 3

   Reference for the set

   Use the finished sprite as a reference (Style mode in the editor) for every matching asset.

4. 4
