# See-Through System

## Overview

A see-through system built on Dithered Transparency that automatically fades out objects obstructing the target.

## Features

* Preset-based configuration — no scripting required
* Supports custom see-through styles via texture maps
* Compatible with all shaders (no modification to occluder shaders required)

## Usage

Drag the **SeeThroughSystem** prefab into the scene.

Then configure the parameters:

* **Camera**The main camera. If left unassigned, the system defaults to Camera.main.
* **Target Object**The object the camera focuses on (e.g., the main character).
* **Target Center**The center point of the target.
  * If the target has no collider, this point is used as the raycast origin.
  * If the target has a collider, this setting is ignored and the collider bounds are used for detection instead.
* **Occluder Layer Mask**Specifies which layers can be treated as occluders (e.g., walls).
* **Fade Time**The duration of the fade transition (controls the fade-in and fade-out timing).
* **See Through Mask Material**The material used for the see-through mask.
  * **Default** – Procedurally generated pattern
  * **Circle** – Circular dot pattern
  * **Square** – Square grid pattern

Run the scene. When the target is obstructed, the blocking objects automatically fade to semi-transparent, allowing the character to remain visible.

## Custom Styles

Create a new **SeeThroughMask** material and adjust its texture and parameters to achieve custom visual styles.
