DMX Channel Layouts
13-Channel Mode (PAR, Blinder, Lightbar)
Standard full-featured control:
| Channel | Function | Range | Description |
|---|
| 1 | Reserved | 0-255 | Future use / compatibility |
| 2 | Reserved | 0-255 | Future use / compatibility |
| 3 | Reserved | 0-255 | Future use / compatibility |
| 4 | Reserved | 0-255 | Future use / compatibility |
| 5 | Red | 0-255 | Red color intensity |
| 6 | Green | 0-255 | Green color intensity |
| 7 | Blue | 0-255 | Blue color intensity |
| 8 | Intensity | 0-255 | Master dimmer |
| 9 | Strobe | 0-255 | Strobe rate (0=off, 1-255=speed) |
| 10 | Reserved | 0-255 | Future use |
| 11 | Reserved | 0-255 | Future use |
| 12 | Reserved | 0-255 | Future use |
| 13 | Reserved | 0-255 | Future use |
Channels 1-4 and 10-13 are reserved for compatibility with the mover channel layout. Static lights only actively use channels 5-9.
5-Channel Mode (PAR, Blinder, Lightbar)
Simplified control for basic fixtures:
| Channel | Function | Range | Description |
|---|
| 1 | Red | 0-255 | Red color intensity |
| 2 | Green | 0-255 | Green color intensity |
| 3 | Blue | 0-255 | Blue color intensity |
| 4 | Intensity | 0-255 | Master dimmer |
| 5 | Strobe | 0-255 | Strobe rate (0=off, 1-255=speed) |
5-channel mode is more efficient for simple setups where the extra reserved channels aren’t needed.
1-Channel Mode (Flasher)
Minimal single-channel control:
| Channel | Function | Range | Description |
|---|
| 1 | Intensity | 0-255 | Master dimmer / strobe rate |
15-Channel Mode (Multi-Lightbar)
Extended control for multi-segment lightbars:
| Channel | Function | Range | Description |
|---|
| 1-4 | Reserved | 0-255 | Compatibility |
| 5 | Red | 0-255 | Master red intensity |
| 6 | Green | 0-255 | Master green intensity |
| 7 | Blue | 0-255 | Master blue intensity |
| 8 | Intensity | 0-255 | Master dimmer |
| 9 | Strobe | 0-255 | Strobe rate |

Configuration Examples
Basic PAR Light Setup
- Place PAR light prefab in scene
- Configure DMX settings:
- DMX Channel: 1 (or 1, 6, 11, etc. for 5CH mode)
- DMX Universe: 1
- Enable DMX Channels: ✓
- Adjust beam settings:
- Cone Width: 3.0 (wider than spotlight)
- Cone Length: 5.0
- Tilt Offset: 90 (aim straight down)
- Position and aim fixture as needed
Flasher Array
For efficient flasher arrays:
enableDMXChannels = true
singleChannelMode = true
dmxChannel = 1, 2, 3, 4... (sequential)
enableStrobe = true
Lightbar Wash
For wide area coverage:
coneWidth = 5.0 // Maximum width
coneLength = 8.0 // Extended reach
tiltOffsetBlue = 45 // Angled for wall wash
finalIntensityVolumetric = 0.3 // Reduce cone visibility
Blinder Effects
For high-intensity strobe effects:
enableStrobe = true
lightColorTint = Color.white * 3.0 // Boost intensity
finalIntensity = 1.0
globalIntensity = 1.0
coneWidth = 4.0 // Wide spread
Aiming and Positioning
Tilt Offset
Use tiltOffsetBlue to aim the fixture:
- 0° - Horizontal forward
- 90° - Straight down
- 180° - Horizontal backward
- 270° - Straight up
Pan Offset
Use panOffsetBlueGreen to rotate the fixture:
- 0° - Forward
- 90° - Right
- 180° - Backward
- 270° - Left
Combined Aiming
Combine both offsets for precise aiming:
tiltOffsetBlue = 45 // 45° down
panOffsetBlueGreen = 30 // 30° to the right
Shaders
Static lights use the following shaders:
VRSL-StaticLight-ProjectionMesh.shader - Light projectionVRSL-StaticLight-LensFlare.shader - Fixture lens effect
Location: Runtime/Shaders/StaticLights/
Lightbar-specific shaders:
Runtime/Shaders/StaticLight-LightBarAndFlashers/
Use Cases
PAR Lights
- Stage Washes - Color washing stages and sets
- Uplighting - Wall and backdrop illumination
- Truss Lighting - Mounted on trusses for overhead coverage
- Floor Lighting - Ground-mounted for uplighting effects
Blinders
- Audience Blinding - High-intensity flash effects
- Strobe Effects - Synchronized strobing
- Impact Moments - Dramatic emphasis
- Photo Flash - Simulated camera flashes
Flashers
- Accent Lighting - Simple on/off effects
- Edge Lighting - Truss and structure outlining
- Strobe Arrays - Large groups of synchronized strobes
- Background Effects - Ambient flashing
Lightbars
- Linear Washes - Continuous line of light
- DJ Booth Lighting - Front-facing wash effects
- Stage Edging - Stage border illumination
- Architectural Lighting - Building facade lighting
Use 5-Channel Mode
When you don’t need the full 13-channel layout:
// Use 5CH prefabs instead of 13CH
// Saves DMX address space and processing
Disable Unused Features
enableStrobe = false // If strobing not needed
finalIntensityVolumetric = 0 // Disable volumetrics if not visible
Component Mode Optimization
finalIntensityComponentMode = true
finalIntensityVolumetric = 0.2 // Reduce volumetric
finalIntensityProjection = 1.0 // Keep projection
finalIntensityFixture = 0.5 // Reduce fixture mesh
Troubleshooting
Fixture Not Lighting
- Check DMX channel assignment
- Verify RGB channels (5-7 in 13CH, 1-3 in 5CH) have values
- Ensure intensity channel is above 0
- Check
enableDMXChannels is enabled
Wrong Colors
- Verify channel offset is correct
- Check universe assignment
- Ensure RGB channel order matches DMX software
- Test with manual color tint to verify fixture works
Strobe Not Working
- Verify
enableStrobe is enabled
- Check strobe channel (9 in 13CH, 5 in 5CH) has value
- Ensure strobe value is above threshold (~20)
- Verify VRSL Grid Reader strobe output is enabled
Flasher Too Dim
- Increase
lightColorTint intensity (HDR value)
- Boost
globalIntensity to 1.0
- Set
finalIntensity to 1.0
- Check single channel mode is enabled correctly
Beam Not Visible
- Increase
coneLength and coneWidth
- Boost
finalIntensityVolumetric
- Ensure post-processing bloom is enabled
- Check fixture isn’t obscured by geometry
AudioLink Integration
AudioLink variants support:
- Band selection for intensity modulation
- Band multiplier for sensitivity
- Color chord sampling
