FAQ

What types of tiles work best?

Organic textures like grass, dirt, sand, lava, stone, and water work great. Structured tiles like brick and cobblestone work well at lower strength settings. Directional tiles (roads, rivers) may need manual editing.

Does it change my tile's colors?

No. The processing snaps every pixel to the nearest color in your original palette. If your tile has 16 colors, the output has the exact same 16 colors.

Can I use this with tiles from other tools?

Yes. Upload any tile image — it doesn't need to be generated with Sprite AI. The seamless processing works on any pixel art tile.

What's the seamless strength slider?

It controls how much edge blending is applied. 0% means no change. 100% is full GEGL seamless blend. For most tiles, 75-100% works well. Lower it if you see diamond-shaped artifacts.
