Nox Prompt Lighting Master

Lighting is where generated images fall apart first - flat light, wrong mood, colors that fight each other. Nox Prompt Lighting Master is the pack's dedicated answer: one node that consolidates light source, quality, time of day, fill, backlight, practicals, atmosphere, and color gel into a single lighting prompt, plus mood notes and technical rigging notes. The README positions it as the "centralized lighting control" companion to the Builder, and the source backs that up - its vocabulary is enormous.

How it works

The constants.py dictionary for light sources alone is worth a look: something like fifty options from Daylight and Soft Light up to Aurora Curtain, Arc Welder, and Supernova Remnant, each mapping to a prompt clause and a summary. That's the whole mechanism in miniature - blueprint and key_style (the two required fields) plus the optional dropdowns resolve to curated prompt fragments, which assemble into lighting_prompt. mood_notes gives you the readable version of the look, and technical_notes collects the rigging language (fill, backlight, gels, practicals, special techniques) that you'd hand to a crew but keep out of the encode.

Two inputs are more interesting than the rest. intensity_bias nudges how strong the lighting reads, and safety_profile carries the pack's habit of safety/comfort guidance into lighting - the constants file even has notes about keeping light intensity softer for all-ages scenes. Every dropdown has a Custom Input option and matching *_custom field.

Inputs and outputs that matter

Required: blueprint and key_style. After that, light_source and time_of_day are the two that change a scene the most, so start there. Outputs: lighting_prompt (feed to Nox Prompt Builder's lighting_prompt input or straight to positive conditioning), mood_notes, technical_notes, and preset_status. Save your favorite setups with preset_action/preset_name - lighting looks are the most reusable thing in this pack.

Installing it

Pack install, once. ComfyUI Manager: search "Nox Prompter", install, restart. Or:

cd ComfyUI/custom_nodes
git clone https://github.com/jamesk9526/NoxPrompter-ComfyUI-CustomNode

Restart, find the NoxPrompter category. Pure Python, no dependencies.

Gotchas

The classic pack-level stale README URL applies. Two practical notes: don't dump technical_notes into the encode - that's production documentation, and models don't understand "Kicker Highlights, featured edge accents" as well as they understand the plain lighting_prompt. And if you're building one master prompt by hand, use this node rather than the Builder's built-in lighting dropdowns - the README's whole point is that centralized lighting means one node owns the light so narrative, palette, and camera fragments don't contradict it. Contradiction detection between lighting and time-of-day is something the Pipeline Combiner actually checks for, which tells you the author expects you to keep it consistent.
