# Fixtures Overview

> Overview of available VRSL fixture types and their capabilities

VRSL provides a comprehensive suite of lighting fixtures designed to emulate professional stage lighting in VRChat. Each fixture type is optimized for performance using GPU instancing and custom shaders.

## Fixture Categories

VRSL fixtures are organized into the following categories:

### Moving Lights

Dynamic fixtures with pan and tilt capabilities:

* **Spotlight** - Focused beam with gobo projection support
* **Washlight** - Wide beam for area coverage

### Static Lights

Fixed-position fixtures for basic lighting:

* **PAR Light** - Classic PAR can with RGB color mixing
* **Blinder** - High-intensity strobe/blinder effects
* **Flasher** - Single-channel strobe fixture
* **Lightbar** - Multi-segment RGB lightbar

### Special Effects

* **Laser** - Laser beam effects with pan/tilt
* **Disco Ball** - Rotating mirror ball projection

## Control Modes

All VRSL fixtures support multiple control modes:

### DMX Mode

Industry-standard DMX512 control via the VRSL Grid Node:

* Channel-based control (1-13 channels depending on fixture)
* Universe support (up to 9 universes in extended mode)
* Horizontal and Vertical grid modes
* Legacy sector-based addressing

### AudioLink Mode

Audio-reactive control via AudioLink integration:

* Frequency band selection
* Amplitude-based intensity
* Color chord sampling
* Theme color support

### Udon Mode

Direct Udon script control:

* Runtime property modification
* Target following for movers
* Animation integration

## Common Features

All VRSL fixtures share these common features:

* **GPU Instancing** - Efficient rendering for multiple fixtures
* **Global Intensity** - Master brightness control
* **Final Intensity** - Per-component brightness limits
* **Color Tinting** - HDR color adjustment
* **Strobe Effects** - DMX-controlled strobing
* **Component Mode** - Separate control for volumetric, projection, and fixture meshes

## DMX Channel Ranges

| Fixture Type | DMX Channels | Notes                     |
| ------------ | ------------ | ------------------------- |
| Spotlight    | 13           | Standard mover            |
| Washlight    | 13           | Standard mover            |
| PAR Light    | 5 or 13      | Simple or full mode       |
| Blinder      | 5 or 13      | Simple or full mode       |
| Lightbar     | 13 or 15     | Standard or multi-segment |
| Laser        | 13           | Full control              |
| Flasher      | 1            | Single channel            |
| Disco Ball   | 1            | Intensity only            |

## Prefab Locations

All fixture prefabs are located in:

```
Packages/com.acchosen.vr-stage-lighting/Runtime/Prefabs/
```

Organized by control mode:

* `DMX/Horizontal Mode/` - Standard DMX fixtures
* `DMX/Vertical Mode/` - Vertical grid variants
* `DMX/Legacy Mode/` - Legacy sector-based fixtures
* `AudioLink/` - AudioLink-enabled variants

## Performance Considerations

* Use 5-channel variants for simple static lights when full DMX features aren't needed
* Enable Final Intensity Component Mode to separately control volumetric brightness
* Disable strobe effects if not needed to save processing
* Use the legacy gobo range option for compatibility with older setups
