Looksmith: Stylized & Toon Rendering for URP

Key features:

• Looks are Volume Profiles: they blend by weight, priority and area (Look Zones), with palette colours blended in OKLCH so cross-fades never pass through grey.
• Lighting model: banded ramps, soft wrap, a three-colour gradient ramp, a textured terminator, flat shading, rim light, and stepped, Blinn or anisotropic hair specular, with a blend toward URP's own lighting. Lightmaps, shadowmask and light probes are respected.
• Art styles run after URP's post-processing, each with an intensity and a rendering-layer mask: Posterize & Palette (OKLab steps, gradient map, palette lookup), Painterly (anisotropic Kuwahara, steady while the camera moves), Watercolour, Ink & Hatching (strokes fixed in the world), Comic (light-adaptive bands and halftone), Pixel Art (quantisation, dither, a Pixel Camera that snaps to the pixel grid), Retro & Lo-Fi (fixed internal resolution, colour depth, CRT and VHS) and Yarn (knitted surfaces, with per-piece baking for your models).
• Lines: screen-space edges from depth, normals, colour and object IDs, with jitter and wobble that stay put in the world and per-layer masks; inverted-hull outlines with baked smooth normals; a jump-flood selection highlight; see-through silhouettes.
• Shaders (Shader Graph): Lit, Lit FX, Unlit, Particles, Terrain (height blend, cliff texture), Character (SDF face shadows, hair highlight) and Grass.
• Restyle: rules for URP, Built-in, Autodesk Interactive and legacy shaders, an opt-in guess for unknown shaders, and manual mappings saved as rules. Materials inside models are extracted first; package materials get copies.
• Sky: nine presets, procedural stars and clouds, sun and moon, and ambient light, fog and a reflection cubemap that follow the sky. Day-night cycle with keyed moods.
• Atmosphere: height fog, ground mist, volumetric sun and moon shafts, cloud shadows and ambient occlusion.
• Water: Gerstner waves mirrored on the CPU with Burst for buoyancy and height queries, an interaction field for ripples and wakes, foam, caustics, refraction, planar reflections, three quality levels and nine presets.
• Grass: a GPU meadow over a terrain, tiled per camera with no per-blade data, five styles, driven by the wind.
• Tweaks: one panel for every setting, drafts with Save and Revert, Undo, and an in-game overlay in Editor Play Mode.
• Safety: previewed changes, backups outside Assets, revert checked file by file (SHA-256) with conflict handling, version-control checkout, Bypass and a project-wide off switch.
• Rendering: RenderGraph passes added per camera at runtime (an optional renderer feature exists), with depth, normals and colour requested automatically. Works with Forward, Forward+, Deferred and Deferred+, MSAA, HDR, TAA, STP and FSR, and camera stacks with a HUD.
• Code: C# source, no DLLs, namespaces under PaleFernStudio.Looksmith, designed to be safe with Domain Reload disabled.

Documentation:

• A 42-page PDF manual with a table of contents (Documentation/Looksmith Manual.pdf): setup, every look and style, the world tools, Restyle, backups, a scripting reference, the Lite and Pro comparison, known limitations and troubleshooting.
• A tooltip on every setting, and ? buttons in the editor that open the manual.

Give your whole game one look. In Looksmith, a Look is a single profile that drives the lighting, colour, lines, haze and finish of everything it styles. Pick one of 18, from a cozy picture book to a worn VHS tape, and your scene follows. Then make it yours.

Every look is a starting point. Change any setting, switch any effect off, stack art styles into a look of your own and save it. The Tweaks panel keeps your changes as drafts until you save them, and it works while the game runs, with an overlay right over the Game view.

What's inside

• 18 Looks and 72 variants: Stylized Realism, Storybook, Oil Painting, Ligne Claire, Cel Anime, Comic Line, Pixel Diorama, Ink & Wash, Sumi-e, Retro 32-bit, Dark Fable, Silent Fog, Lo-Fi Horror, Analog Horror, Wilderness Poster, Watercolour Sketch, Summer Anime and Knitted, with Night, Realistic, Low Poly and Cozy versions.
• Art styles that stack on any look: Posterize & Palette, Painterly, Watercolour, Ink & Hatching, Comic halftone, Pixel Art with a pixel-perfect camera, Retro & Lo-Fi with a CRT or VHS screen, and Yarn, which knits your whole world.
• Lines from depth, normals, colour and object edges, plus hull outlines, a selection highlight and see-through silhouettes.
• Shaders driven by the look: Lit, Lit FX (dissolve, dither fade, hit flash), Unlit, Particles, Terrain, Character (anime face shadows) and Grass.
• Restyle converts your URP, Built-in and legacy materials to Looksmith shaders, with a preview first and a backup.
• Look Zones: a different look per area, blended as the camera moves.

Optional world tools. A sky with nine times of day and a day-night cycle. An atmosphere with height fog, ground mist, sun shafts and cloud shadows. Water with nine presets, buoyancy, ripples and planar reflections. A GPU grass field with five styles, and wind for all of it. Use all of them, some or none: a look doesn't need any of them.

Safe to try. Importing changes nothing outside the Looksmith folder. Your URP asset and renderer need no edits: Looksmith adds its passes to each camera while rendering. Every change it makes to your project is previewed first, backed up, and can be reverted exactly. One switch shows your scene without it.

Two demo scenes. A lakeside village with seven places to find, each in two moods, and the village's centre on its own (Lite's demo). Walk around, flip through the looks and the times of day, and compare with plain URP.

Try it first. Looksmith Lite is free: three of the looks, the lighting, lines, Restyle and the safety tools, in the same files, so importing Pro over it upgrades it in place.

Lite and Pro

• Looks: Lite has 3 (Stylized Realism, Cel Anime, Silent Fog) and 12 variants; Pro has all 18 and 72 variants.
• Art styles: Lite has Posterize & Palette and the Finish; Pro adds Painterly, Watercolour, Ink & Hatching, Comic, Pixel Art, Retro & Lo-Fi and Yarn.
• Lines: Lite draws depth and crease lines; Pro adds colour and object edges, layer masks, hull outlines, a selection highlight and see-through silhouettes.
• Materials: Lite has Lit, Unlit and Particles; Pro adds Character, Terrain and Lit FX.
• Sky: Lite has 3 presets; Pro has 9 and the day-night cycle.
• Pro only: the atmosphere, water, the grass field and Look Zones.
• In both: the lighting model, Tweaks and your own looks, Restyle, previews, backups and exact revert, the Hub, the wind and the manual.

Requirements. URP, 6000.3 or newer. Developed and tested on Windows (DirectX 11 and 12); other platforms haven't been tested yet. Built-in and HDRP aren't supported. A 42-page PDF manual is included, and every setting has a tooltip.
