Ink & Tone is a complete, production-ready stylized post-process framework built for Unreal Engine. Developed around Lumen and native dynamic lighting, it brings traditional printmaking aesthetics, such as pen-and-ink hatching, cel-shading, comic outlines, and atmospheric washes, directly into your viewport with zero light baking required.

Fun and effortless to use, engineered with production depth for creators and professionals.

Originally created for the award-winning Projet Brouillon (Jury Prize at Indie Game Nation 2026), Ink & Tone has been completely refined into an effortless, plug-and-play solution for indie developers and technical artists alike.

What's included in the Toolkit?

Dynamic Shading & Inking Modules

• Customizable Cel-Shading: Powered by curve atlases for endless looks - from razor-sharp comic cuts to soft, analog gradient washes - with built-in fine-art paper texture and contact shadow injection (SSAO).

• Dynamic 3-Tier Hatching: Automated pen strokes spread across soft, intermediate and deep shadow steps. Includes three hand-drawn texture patterns, as well as warp and mask noise parameters for a more natural look.

• Dual Edge-Detection Outlines: Separate depth and normal passes that cleanly capture both outer object silhouettes and subtle internal geometric details.

• Stylized Atmospheric Fog & Cloud Shadows: Extensive solution to add depth-based atmospheric washes for better foreground and background separation.

16+ Distinctive, Production-Ready Presets

Easily jump into production and creation, or find instant inspiration across a wide variety of unique looks, inspired by the drawing medium and other media alike.

Experience an award-winning look with the official Projet Brouillon preset, turn your scene into a singular drawn look with Soft Ink, create a gentle atmosphere with Casper, or pay tribute to old videogames with the Retro asset.

Two original Showcase Maps

Experiment with Ink & Tone's preset and parameters with two distinct levels made specifically to stress test interactions with the post-process and native Unreal Engine techniques:

• Workshop: A cluttered, prop-heavy interior level designed to testcontact shadows, PBR roughness, and hatching density under dynamic, complex lighting.

• Paper Realm: Directly inspired by the worlds of the same name in Projet Brouillon ; a vast landscape with distinctive tiers calibrated to fine-tune thresholds and distance fog falloff

Production Utilities & Documentation

• BP_InkAndTone_Master: Pre-configured with locked manual exposure, disabled specular glare, and tuned Lumen settings to maximize rendering stability out of the box.

• Editor Utility Action (EU_SetStencilValue): Batch-tag any selection of meshes directly in the viewport to exclude them from outlines, hatching, or keep un-graded surface colors.

• Full Technical Documentation: Step-by-step PDF technical bible covering every single exposed parameter, naming conventions, and best practices.
