Simulated Shadow

The simulated shadow shader creates a projected shadow effect that follows objects, useful for adding stylized shadows in toon-shaded scenes.

Main Parameters

Color

The color and opacity of the shadow. The alpha channel controls the overall shadow transparency.

Shadow Width

Controls how far the shadow extends from the object. Higher values create larger shadows.

Shadow Direction

A vector that determines the direction and offset of the shadow:

• X/Y/Z: Direction of the shadow projection
• W: Additional width multiplier for fine-tuning

Shadow Sharpness

Controls how sharply the shadow fades out at its edges. Higher values create more defined shadow edges.

Usage

The simulated shadow shader is particularly useful for:

1. Creating stylized ground shadows for floating objects
2. Adding depth to scenes without complex lighting
3. Emphasizing object placement and grounding

To use the simulated shadow:

1. Create a new material and set its shader to "BerryToon/BerryToonSimulatedShadow"
2. Adjust the shadow color and opacity as needed
3. Set the shadow direction to match your scene's lighting
4. Fine-tune the shadow width and sharpness
