Static Lights

PAR lights, blinders, flashers, and lightbar fixtures

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
10	Segment 1	0-255	Individual segment control
11	Segment 2	0-255	Individual segment control
12	Segment 3	0-255	Individual segment control
13	Segment 4	0-255	Individual segment control
14	Reserved	0-255	Future use
15	Reserved	0-255	Future use

Configuration Examples

Basic PAR Light Setup

1. Place PAR light prefab in scene
2. Configure DMX settings:
   • DMX Channel: 1 (or 1, 6, 11, etc. for 5CH mode)
   • DMX Universe: 1
   • Enable DMX Channels: ✓
3. Adjust beam settings:
   • Cone Width: 3.0 (wider than spotlight)
   • Cone Length: 5.0
   • Tilt Offset: 90 (aim straight down)
4. Position and aim fixture as needed

Flasher Array

For efficient flasher arrays:

enableDMXChannels = true
singleChannelMode = true
dmxChannel = 1, 2, 3, 4... (sequential)
enableStrobe = true

Place multiple flashers and assign sequential channels. Control all from a single DMX range.

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 projection
• VRSL-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

Performance Optimization

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
• Theme color integration
• Per-fixture delay offset

See AudioLink Setup for configuration details.
