Hey everyone,

I’m opening the beta for FieldLux, a projection preflight tool for checking projection setups before install.

It is not a media server or mapping replacement. The goal is to help review projector placement, throw, lens shift, surface coverage, lux distribution, overlap, and possible risk areas before going on site.

For the next 3 months, all features are free after sign-up.

Over the last month, I’ve been improving FieldLux based on feedback from Discord, Reddit DMs, and early testers. I’m keeping it free during open beta because I want real workflow feedback from video engineers, projection techs, media server operators, TDs, and installation teams.

Current features include:

- Real projector, lens, throw, and lens-shift controls

- 3D model, room, surface, photo, and LED wall import

- Absolute, normalized, and deviation lux heatmaps

- 13-point lux diagnostics, hover lux, pixel density, and lens view

- Multi-projector overlap review

- PDF export, cloud share, and read-only client viewer

I’d really appreciate any feedback on what feels useful, confusing, or not trustworthy yet for real production work.

I’ve been beta testing FieldLux, a browser-based projection preflight planner for checking projection setups before going on site.

The goal is not to replace mapping software or media servers. It’s more of a planning / checking layer before production: projector placement, throw feasibility, surface coverage, brightness assumptions, overlap, and setup risk.

The diagnostics / stress-analysis layer is currently locked while I continue validating the assumptions and edge cases with beta feedback.

The long-term goal is to expose simple production-facing states like READY / AT_RISK / NOT_RECOMMENDED so results can be communicated more clearly between clients, technical directors, and install crews, but I’d rather keep that layer limited until the logic is reliable enough.

FieldLux is designed to reduce uncertainty before site visits, not replace on-site calibration or final photometric verification.

I’m opening a few more beta slots for people with real-world projection setups, especially messy ones: awkward surfaces, tight throws, low brightness, multi-projector overlap, temporary installs, touring setups, or client handoff situations.

I’m also keeping a small Discord open for beta feedback, bug reports, and projection workflow discussions:

Happy to share access if you want to test it on a real case.

Hey all,

A month ago I posted the projection planning tool I was building. Got really useful feedback in the comments, kept building, and it's now in closed beta.

A few things that changed since:

- Judgment engine runs on real physics now, not heuristics. Returns READY / AT_RISK / NOT_RECOMMENDED, and when something is off it tells you what to change instead of just flagging it.

- Stress scenarios actually catch the drift you see post-install (lateral, throw, rotation, surface measurement error).

- Added cloud share links so you can hand the analysis to clients or install crews without them needing to install anything.

- PDF tech rider export got cleaner.

Quick recap of what it does for anyone who missed the original post:

- Place real projectors (from a spec database) onto a 3D model, photo, or room walls

- Real-time lux heatmap on the actual surface

- Auto edge blending detection for multi-projector setups

- Stress test the setup and returns a verdict

- Export PDF report + cloud share link

One honest note: the stress analysis logic is still being refined during closed beta, so the scenarios will shift as we collect more install data.

Looking for working TDs, projection designers, and AV integrators to keep breaking it. Closed beta testers who stick around and send real feedback get 1 year free after public launch.

Same kind of questions I asked last time, just updated:

- For multi-projector blends, do you mostly pre-plan the geometry or eyeball it on site?

- What's the planning step you wish was automated the most?

- Anyone tried similar preflight tooling? What worked, what didn't?

Not selling anything — just trying to see if this kind of tool is actually useful outside my own workflow. Would appreciate any thoughts 🙏
