Pixxexa — getting started and how-tos

#What Pixxexa is for

Pixxexa makes pixel-art textures that tile seamlessly: stone walls, grass, sand, wood planks, lava, ice, metal plates, sci-fi panels and more. Pick a material, tweak it with friendly sliders, add details like moss or cracks, and export a tile that repeats without a visible seam.

It's for anyone building game levels or backgrounds who needs good-looking ground and walls fast, from a single tile to a full themed set.

#Your first texture in 5 minutes

1. Open Pixxexa. A Mossy stone texture is already showing, repeated 3×3 so you can see it tile.
2. In the Materials list on the left, click Cobblestone, Grass or any other thumbnail. The texture changes instantly.
3. In the right panel, drag Scale and Roughness until it looks right.
4. Open Overlays and drag Moss or Snow cover up to add weathering.
5. Click Export, keep Tile PNG, choose a scale such as 4× and click Download.

#How-tos

#How to find a material

1. Use the Search materials… box on the left, for example "brick", "lava" or "sci-fi".
2. Or choose a category from the All materials menu.
3. Click the star on a thumbnail to save it as a favourite.
4. Use the dice button next to the search box for a random material, sometimes in a biome's colours.

There are 124 materials, from rough and cracked stone to glowing-mortar bricks, rusted metal, chainmail, marble, mosaic and rune floors. Seventeen of them are animated: lava, water, swamp, storm clouds and more.

#How to change the size and look

1. In the options bar, set the tile size with W and H, or the quick buttons 16, 32, 64 and 128.
2. Change the Seed for a different arrangement of the same material; the dice next to it picks a random seed.
3. In the right panel, adjust Scale, Roughness, Contrast and Edge wear.
4. Use the menus for Light (which side the light comes from), Dither (the dithering style) and Colours, which can recolour the material using any biome palette.

#How to add moss, snow, rust and other details

1. Open Overlays in the right panel.
2. Drag any overlay up: Moss, Lichen, Snow cover, Frost, Rust, Dirt & grime, Ash dust, Sand drift, Cracks, Glowing veins, Vines, Fallen leaves, Flowers, Pebbles, Bones, Puddles, Blood, Scorch, Glowing runes or Sparkles.
3. Each overlay keeps its own colours, so moss stays green on grey stone.

#How to check it tiles

1. Switch the view between Tile, 3×3 and Fill in the options bar.
2. Click Seams to draw the tile edges: green means seamless, red would show a seam.
3. The badge at the top of the canvas says seamless ✓ when the edges match.

#How to try different variations

1. Click Variations in the top bar.
2. You'll see the same texture with 12 different seeds, each shown 2×2 so you can judge how it tiles.
3. Click one to use it, or More for another dozen.

#How to make a whole biome texture pack

1. Click Biomes in the top bar.
2. Pick one of the 50 biomes on the left, for example Magma Caldera or Frozen Peaks.
3. Pixxexa builds a matching set: a Ground texture, a Wall, an Accent, an Animated texture and a see-through Detail layer, plus transitions such as Wall top, Floor edge, Trim band and Trim frame.
4. Choose the tile size (16, 32 or 64 px) and re-roll if you want a different take.
5. Click any texture to open it for editing, or Export pack (.zip) to download everything at once.

#How to make transition and edge tiles

1. Click Edge set in the top bar.
2. Choose a tab: Corner 16, Blob 47 (a full autotile set), Wall top, Floor edge or Trim.
3. Pick the Other texture your current one should blend into, for example Dirt.
4. Adjust Ragged edge for a rougher or cleaner border, then click Download.

#How to build a texture by hand

1. In the Layers panel, click + to add a generator (noise, bricks, wood grain, cells, stars…) or an operator (blur, emboss, levels…).
2. Layers draw from the bottom up; operators change everything below them.
3. Set each layer's blend and opacity, reorder with the arrows, or delete with the bin.
4. Hand edits to a material's layers are replaced if you move that material's sliders again.

#How to turn your own image into a tile

1. Click Import in the top bar.
2. Drop, paste or pick an image. It's scaled to the tile size.
3. Choose Blend edges or Mirror to hide the seams, then download it or use it as a layer.

#How to animate a material

1. Pick an animated material (use the Animated filter in the browser), or add scrolling, boil or colour cycling to your own recipe.
2. Press Space to play and pause, and the arrow keys to step frames.
3. Animations always loop seamlessly.

#Exporting and sharing

Click Export (Ctrl+S) and choose a tab:

Pick a scale from 1× to 8× and click Download.

Send to App shares the tile (image), the 8 variants (sheet), the animation (frames) or the colour ramp (palette). Library opens an image to make it tile, or a palette as the colour ramp.

#Tips and shortcuts

• R new seed · V variations · Space play · ← / → step · 1 / 3 / F tile, 3×3 or fill view · S seam lines · 0 fit · Ctrl+Z / Ctrl+Y undo and redo.
• The same material, settings and seed always give the same texture.
• Your recipe autosaves on this device; sign in and use Cloud to keep it across devices.

#Troubleshooting

• If you edited a layer and it reset, you moved a material slider afterwards. Click Detach at the bottom of the material panel first to keep your hand edits. Reset material goes back to the material's own settings.
• If the texture looks noisy, lower Roughness or switch Dither off.
• If colours band in the GIF, export APNG instead.
• If a biome pack takes a moment, wait for the thumbnails to fill in; large packs build several textures at once.
