Release Notes

v1.1.0 — 13 September 2026

Lumentrace is now free. Licensing is gone: no activation, no demo mode, no feature limits. Trackers, patched fixtures, saving and loading, and session length are unrestricted for everyone.

New

• Beam trim. An Iris Offset / Zoom Offset fader beside the pan and tilt offsets, to correct a rushed beam calibration during the show without recalibrating. The trim is saved with the project and is mappable from MIDI and DMX input.
• Update banner. Lumentrace now tells you when a newer version is available, as the Client already did. Before, a new release was only visible through Help → Check for Updates.

Licensing removed

• The License & Activation window and its Help menu entry are gone.
• No licence key, account or internet connection is needed to use the app.
• Leftover activation files are removed from the app's data directory on first launch.
• If you were running a preview licence, there is nothing to do — install 1.1.0.

Improved

• Art-Net and sACN output recovers on its own when a network interface drops and comes back, instead of staying silent until you restart.
• Lumentrace now says why output is not running — no interface selected, an interface this machine no longer has, or an sACN socket that could not start — rather than failing quietly.
• Error and alert text can be selected and copied.
• Projects saved by older versions open normally instead of being refused.

Fixed

• Closing with unsaved changes now asks before discarding the project.
• Clicking a mesh point recalls the calibrated beam size for that point again.
• A camera feed no longer freezes when its source stops and returns.
• Releasing a fixture in Direct Output mode fades, instead of snapping to zero.
• Check for Updates offers the installer for the platform you are running.

Upgrading

• Server and Client must match on major.minor, so update every machine together: a 1.0.x Client cannot connect to a 1.1.0 server. See Version Compatibility.
• On macOS, re-grant Camera and Local Network afterwards: every update resets them, and until you do no cameras appear and discovery finds nothing. See Updating on macOS.

v1.0.0 — 19 June 2026

Lumentrace 1.0 is the initial public release.

Lumentrace turns any moving light into an automated followspot. A camera feed is placed on a canvas, calibrated to the stage once, and Lumentrace drives pan, tilt, intensity, and beam size over Art-Net or sACN in real time.

Tracking

• Real-time performer tracking from any camera source: local USB/capture card, NDI, RTSP, SRT.
• Multiple trackers per project, each independently assignable to fixtures.
• Rise Mode for vertical compensation (stairs, platforms) via scroll wheel.
• Free Move for manual override without losing calibration.
• Intensity Masks: define regions of the canvas where intensity is automatically reduced.

Calibration

• Calibration mesh maps camera coordinates to DMX pan and tilt values.
• Minimum 3 mesh points; accuracy improves with more points.
• Beam Size Compensation calibration per mesh point (Iris, Zoom, Zoom + Focus).
• Pan and tilt offsets for fine correction without full recalibration.

DMX output

• Art-Net and sACN output on configurable universes.
• Direct Output and Merge modes with per-attribute control.
• Show Mode toggle for clean HTP merge alongside a console.
• sACN priority failsafe topology for automatic console fallback.
• Crossfade time for smooth release fades.

Fixture management

• GDTF import and custom fixture builder.
• Five preloaded factory profiles (Ayrton, Clay Paky, Prolights, Robe Lighting).
• Multi-fixture patch with address conflict detection.

Remote operation

• Lumentrace Client: remote operator app for macOS and Windows.
• Up to 64 simultaneous clients over local network.
• Per-tracker locking — each operator holds their own tracker independently.
• Real-time bidirectional tracker sync between server and all clients.

External control

• MIDI CC and Note mapping for presets, fixture attributes, and pan/tilt offsets.
• DMX input mapping on a dedicated control universe.
