Drop your texture atlas, choose the tile size, and slice it into editable elements.
Right-click any element afterwards to make it seamless, build transitions or assign materials.

Slice Atlas cuts the whole image on a uniform grid. Pick tiles… lets you set the grid and choose which cells to import — great for ripping one texture or stitching from several atlases.

No atlas yet? Create a blank one (using the tile size above) and add textures one at a time.
2️⃣ Atlas Elements
🖱️Right-click an element: Make Seamless · Make Transition with Texture · Set Material.
Transition tiles are appended below the atlas and inherit their parents' materials.
🔒 Base texture locked — now click a second element to build the transition
🗑️ Delete mode — click tiles to select (0 selected)

🔄 Make Seamless — Tile
🔀 Make Transition — Tile → Tile
Base (A)
→
Overlay (B)
Paint white where the overlay (B) should show through. The mask is softened automatically. One tile is added.
🩹 Heal / Fill — Tile
🫥 Fade to Transparent — Tile
Fades part of the tile to nothing (alpha → 0). Great for decals — cobwebs, dust, leaves, foliage — that should blend into the surface instead of ending at a hard edge.
Paint where the tile should fade to transparent.
✨ Make Emissive — Tile
Authors a glow (emissive) map for this tile — areas that shine on their own, independent of scene lighting. Pick what glows, then how it's coloured. Black = no emission.
Tip: click the source preview to eyedrop the target colour from the tile.
Tip: click the source preview to set the hue from a pixel. Good for lava, poison, crystal, neon.
Paint directly on the source preview where the tile should glow.
📐 Anchored Transition — Tile → Tile
The border between the two textures is a chain of anchors. Start from a preset, then drag anchors to bend the border, click empty space to add one, or right-click an anchor to remove it. Overlay (B) fills one side.
🗺️ Transition Grid — Tile → Tile
Design one continuous A→B border across a whole wall, then slice it into tiles. Set the grid size, drag the anchors (click empty space to add, right-click to remove); the border flows across cell edges so the tiles connect seamlessly. Add drops one transition tile per cell into the atlas.
🗺️ Import Tiles
Set the grid that matches the source image, then click cells to choose which tiles to import. Selected cells are added to your atlas (each resized to 256²).

🧩 Wang Set — Tile → Tile
Generates the 16-tile edge set so the overlay terrain connects in every up/down/left/right combination. Tiles inherit materials from the two sources.
✨ Generate Variations — Tile
Creates jittered copies (hue / brightness / rotation) appended to the atlas — handy for breaking up obvious tiling repetition.
🎨 Set Material — Tile
⚙️ Advanced editor (tweaking creates a custom material)
