# Changing MUs

Components for dynamically modifying MU (Movable Unit) appearance, materials, and behavior during simulation.

## Available Components

### Visual Modifications

* [**PartChanger**](/components-and-scripts/changing-mus/partchanger.md) - Changes the visual appearance of MUs by switching between predefined appearances
* [**MUSwitcher**](/components-and-scripts/changing-mus/muswitcher.md) - Controls visibility of grouped GameObjects within MUs based on sensor detection
* [**MaterialChanger**](/components-and-scripts/changing-mus/materialchanger.md) - Dynamically changes materials on MU components

### Processing Operations

* [**Cutter**](/components-and-scripts/changing-mus/cutter.md) - Simulates cutting operations on MUs with visual feedback

## Key Features

* **Sensor Integration**: Changes triggered by sensor detection events
* **PLC Integration**: Control via PLCInputBool signals for industrial automation
* **Visual Feedback**: Real-time appearance changes during simulation
* **Logic Integration**: Works with Logic Steps and automation sequences
