Introduction: Seeing the Show Before It Happens

In modern lighting design, imagination meets simulation. Visualizers allow designers and programmers to pre-program full lighting sequences in a 3D environment long before the rig is flown or the truss is assembled. Whether for a concert tour, corporate event, theatrical production, or broadcast, visualizers have transformed the workflow from reactive to proactive.

By rendering a digital twin of the stage and fixtures, visualizers save time, reduce on-site stress, and enable tighter artistic control. This guide explores how to effectively use lighting visualizers for pre-show programming—from setup to showtime.


What Is a Lighting Visualizer?

A lighting visualizer is a software platform that creates a 3D representation of your venue, set, and fixtures. It emulates how lights behave in real space, displaying beams, shadows, colors, gobos, and effects in real time.

Popular visualizer platforms include:

  • Depence²

  • Capture

  • WYSIWYG

  • grandMA 3D

  • Vision by Vectorworks

  • LightConverse

These tools integrate with lighting consoles or software over protocols like Art-Net or sACN to simulate real-world DMX behavior.


Benefits of Pre-Show Visualizing

Time Savings

Programming cues on-site can be time-consuming and rushed. With visualizers, you can create full cue stacks before arrival, requiring only minor adjustments at the venue.

Creative Freedom

Offline programming allows deeper experimentation. Designers can test effects, sequences, and transitions without the pressure of rental hours or rehearsals.

Team Communication

Visual previews allow directors, choreographers, and clients to sign off on looks before the show begins, ensuring better alignment across departments.

Error Reduction

Issues like patching errors, blocked angles, or poor fixture placement can be spotted and fixed virtually—before they become real problems.


Getting Started: Building Your Virtual Stage

1. Import Venue Geometry

Most visualizers allow importing 3D venue models in formats like DWG, OBJ, or 3DS. Some include venue libraries for common halls and arenas.

If unavailable, build a basic structure using built-in geometry tools:

  • Stage floor and risers

  • Truss positions

  • Backdrops or cyc walls

  • Scenic elements

2. Place Fixtures Accurately

Use precise coordinates or drag-and-drop tools to position fixtures:

  • Hanging positions: truss, pipe, side booms

  • Floor placements: uplights, towers, footlights

  • Orientation: tilt and pan based on rigging angle

Enter channel numbers, universe assignments, and DMX modes for each unit to match the real patch.

3. Import or Build Set Pieces

For theatre and show production, include scenic elements. Materials with different reflectivity will affect how light behaves—just like real life.


Programming with a Console or Software

Once the virtual rig is built, connect your console or controller via:

  • Art-Net/sACN output

  • Loopback interfaces (for onPC systems)

  • Direct integration with platforms like MA3, ETC Nomad, or Chamsys MagicQ

Cue programming in the visualizer follows the same workflow as on-site. You can:

  • Write cues, chases, and effects

  • Preview beam paths and coverage

  • Visualize gobo and prism combinations

  • Simulate strobe, iris, or shutter timing

  • Fade between looks and adjust transitions

Most visualizers allow recording screen videos or stills for previews and presentations.


Optimizing Realism and Performance

Use Beam Quality Settings

Higher-end visualizers simulate volumetric light, haze behavior, and reflections. Adjust beam density, edge softness, and diffusion to match the actual show.

For smoother playback, lower rendering settings when writing cues and raise them for final previews.

Add Haze or Atmosphere

Fog simulation reveals beam angles and cross patterns, helping assess impact positions and visual layering.

Layer Fixtures in Groups

Label fixtures by role (e.g., "Downstage Wash," "Gobo FX," "Backlight FX") to toggle visibility during programming.


Common Use Cases by Show Type

Concerts and Tours

Build your touring rig once and adapt layouts for different venue sizes. Pre-program scenes for the full setlist and export cue sheets for each stop.

Theater and Opera

Sync visual cues with script lines or choreography. Explore subtle cue transitions, cue timings, and focus positions.

Corporate Events

Preview logo projections, wall washes, or camera-friendly lighting arrangements. Show stakeholders visual mockups during planning.

Broadcast or Film

Simulate how lighting appears on camera angles. Adjust for camera color temperature, diffusion levels, and flicker-free dimming.


Collaborative Workflow Tips

  • Use Screen Recording to Present Looks to clients or creative teams

  • Create a Master File for the entire rig and distribute clone copies per programmer or department

  • Back Up Often and version files (e.g., “ShowName_Presets_v3”)

  • Export Patch Lists and Fixture Reports directly from the visualizer for on-site reference


Troubleshooting Visualizer Issues

No Output Visible?

  • Ensure universe/DMX address settings match

  • Verify Art-Net output is enabled

  • Check fixture orientation and intensity levels

Laggy Playback?

  • Reduce beam render quality

  • Hide unused fixtures

  • Upgrade your graphics card or run visualizer on a separate machine

Fixture Not Acting as Expected?

  • Verify correct DMX mode and personality

  • Update fixture library files

  • Check for console and software compatibility


Final Steps Before the Real Show

Before arriving on site, ensure:

  • All fixture positions and patching match the final plan

  • You’ve exported fixture reports and console showfiles

  • Backup USBs and cloud copies are ready

  • Visualizer videos are available for client reference or pre-vis approval

Once at the venue, transferring cues into the actual system should take minimal time—leaving you free to adjust for truss height, ambient light, or client tweaks.


Conclusion: Visualize to Maximize

Lighting visualizers empower designers to create confidently, communicate clearly, and program efficiently. Whether building from scratch or refining an established design, visualizers offer a creative sandbox and a technical blueprint—all in one.

As live productions demand ever tighter timelines and higher expectations, pre-show visual programming gives lighting teams the edge. You don’t just light the show—you visualize it into reality.
