System Architecture

CelShaderFX provides two ways to use the effects:

Simple Mode (Recommended for Most Users)

Uses a single settings asset with all effects in one place.

CelShaderSettings (ScriptableObject)
    └── All effect parameters
    └── Applied via CelPostProcessEffect / Volume

Best for:

• Quick setup
• Static effect configurations
• Artists who prefer a unified interface

Advanced Modular Mode

Uses individual modules with a controller for runtime manipulation.

    ├── CelShadingModule
    ├── OutlineModule
    ├── HatchingModule
    ├── DitheringModule
    ├── HalftoneModule
    ├── WatercolorModule

Object Cel Shading

Object Cel Shading is a per-object material-replacement shader that applies cel shading, hatching, outlines, and stylized lighting directly to individual meshes. Unlike the post-process effects which operate on the full screen, Object Cel Shading uses the object’s own UVs and geometry, producing stable hatching lines that stick to surfaces without swimming.

Works on all three pipelines: Built-In, URP, and HDRP.

Pro and Ultimate: three Object Cel Shading setups in one scene, each head shaded on its own.

Setup

1. Select a GameObject with a Renderer (MeshRenderer, SkinnedMeshRenderer)
2. Add Component > CelShaderFX > Object Cel Shading
3. The component automatically replaces the object’s material with the cel shading shader

The component uses MaterialPropertyBlock for per-instance GPU instancing, so multiple objects can share the same shader with different settings at no extra draw call cost.

The Add Component menu on an object, with Object Cel Shading highlighted.

Post-Process Exclusion

When using Object Cel Shading alongside the post-process effects, enable Exclude From Post Process (on by default) to prevent double outlines and double cel shading on the same object.

Parameter	Range	Default	Description
Use Hatching	bool	true	Enable hatching overlay
Density	1-400	20	Line frequency
Rotation	-PI to PI	0.785	Primary line angle (radians)
Secondary Angle	0.52-1.57	1.57	Cross-hatch angle offset
Layers	1-4	3	Number of hatching layers
Hatching Mode	enum	Combined	Screen, Object, or Combined space

Line Appearance

Parameter	Range	Default	Description
Line Thickness	0.1-1	0.4	Line width
Line Spacing	0.5-3	1.0	Space between lines
Line Wobble	0-1	0.3	Hand-drawn irregularity
Line Taper	0-1	0.2	Taper at line ends
Line Color	Color	Dark gray	Color of hatching lines

UV Settings

Mode	Description
UV0	Standard mesh UVs
Triplanar	World-space projection for objects without good UVs

For triplanar mode, adjust Triplanar Scale and Triplanar Sharpness to control the projection.

Toon Lighting

Controls how light and shadow are rendered on the object.

Parameter	Range	Default	Description
Ramp Threshold	0-1	0.5	Light/shadow boundary position
Ramp Smoothness	0.001-1	0.01	Transition sharpness

Creating Presets

Save and share your effect configurations.

Creating a Preset

1. Configure your effects as desired
2. Right-click in Project window
3. Create > CelShaderFX > Preset
4. Name your preset
5. Click Capture Current Settings in the Inspector

Create Preset

Applying a Preset

using CelShaderFX;

// Load and apply preset
var preset = Resources.Load<CelShaderPreset>("Presets/MyPreset");
preset.ApplyTo(settings);

// Or with interpolation
preset.ApplyTo(settings, 0.5f); // 50% blend

Preset Interpolation

Smoothly transition between presets:

IEnumerator TransitionPreset(CelShaderPreset target, float duration)
{
    float elapsed = 0;
    var startSettings = CaptureCurrentSettings();

    while (elapsed < duration)
    {
        elapsed += Time.deltaTime;
        float t = elapsed / duration;
        target.ApplyTo(settings, t);
        yield return null;
    }
}

Performance Optimization

Quality Presets

CelShaderFX includes quality presets for different hardware:

Preset	Target	Key Settings
Mobile	Mobile/Low-end	Kuwahara disabled, simplified outlines
Low	Integrated GPU	Kuwahara radius 2, basic effects
Medium	Mid-range GPU	Kuwahara radius 3, all effects
High	Dedicated GPU	Kuwahara radius 4, full quality
Ultra	High-end GPU	Kuwahara radius 6+, maximum quality

Performance Tips

1. Kuwahara Radius: Each +1 radius roughly doubles cost
2. Disable Unused Effects: Toggle off effects you don’t use
3. Hatching Layers: Fewer layers = better performance
4. Outline Method: Sobel is fastest, Canny is slowest
5. Anisotropic Kuwahara: Most expensive variant

Profiling

Use Unity’s Profiler to measure CelShaderFX impact:

1. Open Window > Analysis > Profiler
2. Look for “CelShaderFX” in the GPU section
3. Individual effects are labeled for identification

---

Best Practices

Combining Effects

Some effects work well together, others conflict:

Combination	Result	Recommendation
Cel + Outline	Classic anime	✅ Recommended
Kuwahara + Painterly	Oil painting	✅ Recommended
Hatching + Dithering	Muddy result	❌ Avoid
Halftone + Dithering	Conflicting patterns	❌ Avoid
Watercolor + Kuwahara	Soft painting	✅ Recommended

Effect Order

Effects are applied in a specific order for best results:

1. Kuwahara (smoothing)
2. Cel Shading (color quantization)
3. Hatching (pattern overlay)
4. Dithering (color reduction)
5. Halftone (pattern overlay)
6. Watercolor (stylization)
7. Painterly (stylization)
8. Outline (drawn last, on top)

Common Mistakes

Mistake	Solution
Effects look different in URP/HDRP	Ensure Volume is set to Global mode
Hatching swims during movement	Increase world space weight
Outlines too thick on small objects	Enable distance fade
Performance issues	Reduce Kuwahara radius first
Colors look wrong	Check color space (Linear vs Gamma)
