Boon Shader Studio is a tool that provides an interface for applying and configuring anime-style materials in EEVEE. It applies a customizable toon shader to existing materials in a non-destructive manner, offering dedicated controls for outline thickness, edge highlights, and rim lighting. The tool maps these properties to a dedicated sidebar panel, allowing users to adjust properties independently for each material.

The tool includes two specialized modules. The Hatching Studio adds printable-style screen effects to the material, including manga halftones, stippled dotted lines, and hand-drawn cross-hatching. The Smear Studio system generates geometry node-driven smear meshes to simulate traditional animation smears on fast-moving objects. The smear effect includes speed thresholds, noise pattern adjustments, and vertex group masking to limit the distortion to specific parts of a mesh. Both the shaders and smears respond dynamically to real-time EEVEE scene lighting.
