Bleed-Through Logic

About

Bleed-Through Logic is a small independent studio working on Yutopia, a stylized board game inspired by Korean yutnori. Because we build our own art pipeline, everything we publish is already shipping inside a real project: the Stylized Planet Toolkit drives the world map of our own game, and the same pipeline produced the tools we are preparing next.

If something we sell breaks in your Unity version, tell us and we will fix it - support is handled by the same people who wrote the code.

Stylized Planet ToolkitUnity URP

Procedural generation of flat-shaded, stylized planets, moons, rings and debris belts for URP projects - then a one-click bake into ordinary prefabs, meshes and materials, so shipping builds pay no procedural generation cost. Pick one of 12 presets, drag a few sliders, press Bake & Save As Prefab.

What it does

12 editable presets: Real Earth, Moon, Mars, Ice, Desert, Lava, Gas Giant, Toxic, Crystal, Ocean, Alien and a random Earth.
Seam-free icosphere terrain - 3D fBm noise, mountain sharpness, flat oceans and coastal cliffs. No UV seam, no pole pinching.
Terrain styles: standard low-poly, terraced steps and gas-giant bands.
Procedural impact craters with count, radius, depth, raised rims and a seed.
Emission masks for lava lowlands, city lights and glowing cracks.
Cloud shells, solid ring systems, seeded debris belts (15-200 chunks) and tidally locked moons.
Flat-shaded vertex-colour surface shader plus an additive Fresnel atmosphere shader.
Auto Fit shells - atmosphere and cloud radii are measured from the generated peaks.
Landmass Mask Baker: real continents from the bundled public-domain Natural Earth data, your own GeoJSON, or procedural noise.
Batch bake of all 12 presets, with stale sub-assets cleaned up and prefab GUIDs preserved.

Gallery

Twelve presets, one toolkit - every planet is generated, then baked into prefabs, meshes and materials.

Emission masks: lava lowlands, glowing cracks and city lights on the night side.

Biome variety from the same generator: ice, desert and alien palettes.

Games

Yutopia - in development

A stylized board game inspired by Korean yutnori: throw the sticks, race the board, and watch the world map change under your feet. The world map is built with the same toolkit we publish. The two captures below are from the current build.

Yutopia in play - throw the yut, move a piece, capture and stack on a raised island board.

Yutopia in development - the camera follows the moving piece while the planet board changes underneath.
