Light Models

The All In 1 3D Shader offers a completely personalizable lighting system that can be mixed and matched to fit your specific project needs. Unlike traditional shaders that restrict you to a single lighting approach, this system provides the flexibility to combine different lighting components for your desired visual style.

Light Model options:

• Classic: Standard lighting calculation suitable for most scenarios

• Toon: Creates stylized cel-shaded look with hard edges between light and shadow

• ToonRamp: Uses gradient texture for more control over shading steps

• HalfLambert: Softer lighting that wraps around objects more than classic model

• FakeGI: Simulates global illumination by brightening shadowed areas

• FastLighting: Explained over Fast Lighting

Shading Model options:

• Basic: Simpler lighting calculations for standard scenarios

• PBR: Physically Based Rendering for realistic material simulation with properties like:

  • Metallic: Controls how metal-like surfaces appear (0-1)

  • Smoothness: Determines reflection sharpness and microsurface detail

Specular Model options:

• Classic: Traditional Blinn-Phong specular model

• Toon: Hard-edged highlights for cartoon styles

• Anisotropic: Stretched highlights following a direction (great for hair, brushed metals)

• AnisotropicToon: Combines anisotropic highlights with toon-style hard edges

Additional features include Reflection systems for environmental reflections, Normal Mapping for surface detail, and customizable Shadow options. The real power comes from mixing these different components - for example, pairing a Toon Light Model with PBR Shading for a unique stylized look, or combining Classic lighting with Anisotropic specular for realistic materials like hair or fabric.
