Linocut — Two-Ink Shader for URP

A URP shader that shades meshes in two flat colors, like a linocut print. Realtime lights and shadows decide where each color goes. Includes four demo scenes.

Flat two-color shading driven by realtime lights and shadows

Any two colors per material

Works with Directional, Point and Spot lights

Optional normal maps for fine relief

Curved Relief mode with a curvature baker for smooth forms

Style Profiles to share one palette across many materials

Custom material Inspector

Linocut shades opaque meshes in two colors. Surfaces that get enough light use the light ink, everything else uses the shadow ink. Your lights, shadows and normal maps decide the shape of the lit areas.

Put a Two Ink material on a mesh in a URP scene and pick two colors. Light Threshold sets how much of the surface turns light. Surface Exposure balances materials against each other, and Facet Power sets how sharp the light edges are. When you move a light, the ink follows it.

Demo scenes

Forest, Hall, Courtyard and Gallery, each with camera views and a settings panel in Play Mode. Gallery has the marble bust, lion head and horse head from the trailer. The other sculptures and sets in the trailer are not included.

Limits

URP with the Forward or Forward+ renderer. Opaque surfaces only. The shader doesn't support transparency, alpha cutout, lightmaps, probes, specular, cookies or color textures.
