What it does.

Volumetric lights and fog feeding into the cel-shaded output
Comic-inspired stippled band transitions
Color-aware outline tinting per surface color
Volume-driven smooth style blending across zones
Back-anchored rim light with Fresnel modulation
Features

The capability set.

Per-actor opt-in

Set CustomDepth Stencil Value on a mesh component. The cel-shading pass treats only that actor; everything else renders as standard PBR.

Non-Stencil Full-screen mode

Toggle bAffectWholeScreen to skip per-actor setup. Every visible pixel is cel-shaded. Useful for prototyping and fully-stylized projects.

Pipeline-aware

Lumen GI, shadow maps, exponential height fog, volumetric fog and volumetric lights all participate in the cel-shaded output. No GBuffer override.

Shading-model agnostic

DefaultLit, Subsurface, SubsurfaceProfile, Cloth, Hair, Eye, ClearCoat — every UE shading model works as-is. The pass gates pixels; it does not touch your materials.

Outline, rim & halftone

Adaptive Laplacian outline with optional Color-aware tinting. Directional rim light with Fresnel and sun-anchored mode. Manga-style halftone screentone overlay.

Volumes, tabs & presets

ACelshadingVolume with bounded or global reach + smooth spatial blending. Custom Details panel groups every override into five tabs — Cel · Outline & Rim · Pattern · Atmosphere · Stencil — with per-group Reset and one-click style reset. UCelshadingPreset DataAssets for reusable looks.

Predictable GPU cost

One compute dispatch per active stencil slot (1..255 — pay only for what you place). Empty slots cost zero, and the whole effect has its own Celshading row in stat gpu — budget it like any other post pass.

No engine fork

Standard plugin. Drops onto stock Unreal — no 100 GB custom engine repo to clone, re-fork or maintain. Auditable C++ and USF source included. No editor patching, no marketplace dependency chain.

What's in the box

Five included presets.

Comix preset — Western comic-book finish Comix
Black Shades preset — high-contrast hard cel Black Shades
Manga preset — sprite-anchored screentones Manga
Strokes preset — 45° hatching transitions Strokes
Anime preset — multi-band cel with sun-anchored rim Anime

Every preset is a UCelshadingPreset DataAsset. Fork it, layer it, or blend several together.

For project leads

No 100 GB engine fork. No hacks.

Production-grade cel-shading that runs on stock Unreal. Pay once at the plugin layer instead of carrying a 100 GB custom engine repo across the whole team.

WITH AN ENGINE FORK
  • ✕  Every artist clones a 100+ GB custom Unreal repo.
  • ✕  Re-fork & re-merge on every UE point release.
  • ✕  CI/CD pipelines must mirror the fork.
  • ✕  Source-locked talent — only your TAs can iterate.
  • ✕  Marketplace plugins drift out of sync.
  • ✕  Project locked to whichever UE version was forked.
WITH ULTIMATE CEL-SHADING PBR
  • ✓  Drop the plugin in — stock Unreal stays stock.
  • ✓  Engine upgrades are normal, not a project event.
  • ✓  Any UE-licensed dev can iterate the look.
  • ✓  Marketplace plugins keep working unchanged.
  • ✓  Editor, PIE and packaged builds — one look.
  • ✓  Auditable C++ and USF source, no obfuscation.

Pay the plugin license once · skip the team-wide fork burden · an engine upgrade becomes a plugin update, not a re-fork.
