Environment (WildPromptor) — scene and setting keywords from dropdowns
- prompt
This is the "where is this happening" node. It's a bank of dropdowns full of settings, landscapes, buildings, weather, and eras - you pick one (or randomize it), and it spits out a location fragment you fold into your positive prompt. If you keep landing on the same three backdrops because you can't think of a fourth, this is a decent idea generator.
It ships in the WildPromptor pack by 1038lab, the developer of the popular ComfyUI-RMBG background-removal nodes.
How it works
Like every list node in this pack, Environment reads a folder of .txt files - here data/Environment - and turns each file into a dropdown. And there are a lot of them: Outdoor (246 lines), Landscapes (272), Landmark (a staggering 1,079), plus themed sets like Horror Environments, Weather and Sky, Future Scenes, Historical Eras, Indoor, War Environments, and Chinese Lunar New Year.
Each dropdown starts with the same three controls before the real entries:
- ❌disabled - ignore this category
- 🎲Random - roll a random line (seed-reproducible)
- 🔢ordered - walk the list in sequence across a batch
Enable the categories you want, pick or randomize each, and the node joins the results into one string.
Inputs and outputs worth knowing
The category dropdowns do the work. The only other controls are batch_size (how many prompts to generate), seed (locks the random rolls), and allow_duplicates (whether a batch may repeat a pick).
The output is prompt, a STRING list. You rarely wire this straight into an encoder on its own - a scene with no subject is half a picture. The intended flow is to run it into the environment slot of the pack's Prompt Concat node, alongside a Subject and a Virtual fragment, and let Concat stitch the full prompt together.
An honest take on the giant lists
The curation is uneven. Some categories are genuinely useful - Indoor and Builds are clean, concrete location lists. Others are padded with fantasy word-salad ("At the Astral Apex atop the Elemental Convergence Spire," which appears twice), and the 1,079-entry Landmark list is more of a gazetteer than something you'll scroll by hand. Treat the dropdowns as inspiration you skim, not a menu you read end to end.
One thing that carries across model families: naming a real, concrete place or setting is prompt gold, because modern text encoders were trained on real captions. "Abandoned subway station with flickering lights" gives the model something specific to latch onto. Vague mood words ("mysterious atmosphere") don't. The best entries here are the specific ones.
Installing it
Via ComfyUI Manager: search ComfyUI-WildPromptor, install, restart. Or clone it:
cd ComfyUI/custom_nodes
git clone https://github.com/1038lab/ComfyUI-WildPromptor
and restart ComfyUI. Nodes show up under 🧪AILab/🧿WildPromptor. The list nodes need no model downloads.
Common issues
- Nodes don't appear - restart ComfyUI completely; they live under the 🧪AILab category, not the root menu.
- Your added categories aren't showing - the node reads the folder at startup. Drop new
.txtfiles intodata/Environmentand restart to re-scan. - Custom file order looks scrambled in the UI - a known quirk: lists you add to
dataaren't always displayed in the order you wrote them. Don't rely on line order for anything but the built-in 🔢ordered mode. - You can't see what Random picked - add the Show Prompt node downstream to read the resolved text.
