✨ Qwen-Image 2.1 After Dark — 4-Mode Auto-Prompt Glamour Workflow (NSFW, 16GB)

ComfyUI · Qwen-Image 2.1 · one control panel · Built with Qwen

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔞 Mature content (18+). This is the adult version of my SFW workflow: https://civarchive.com/models/2967203 . It can produce lingerie, swimwear, topless and fully nude portraits of ONE adult woman. Every subject is a fictional, AI-generated adult (mid 20s); the prompt states her age and no real person is depicted. You are responsible for following Civitai's terms and the laws where you live. Do not use it to depict real people.

Pick a MODE, press Queue, get a finished 4:5 portrait. The workflow writes its own prompt: a built-in list of about 100 scene ideas per mode is expanded by Qwen3-VL 8B running inside ComfyUI into a detailed photographic paragraph, a clothing guard keeps every image inside the MODE you chose, and Qwen-Image 2.1 renders it. No LoRA is included or needed. Tested on an RTX 5080 16 GB.

⚡ Speed at a glance

• Default = max quality: 1792×2240, 25 steps, about 70 s per image on an RTX 5080 16 GB. The first run is slower while the 8B prompt expander loads; later runs reuse it.

• Faster: use the FAST switch in the CONTROL PANEL (v1.1) — 1 Fast (16 steps, no LoRA) renders in about 40 s, vs about 68 s at Quality (measured, RTX 5080, 32 test images) — about 1.7x quicker. For final images we still recommend Quality: in our test, Fast occasionally softened or doubled a limb/edge on 2 of 32 renders (both from the same MODE1 test seeds), an effect absent at Quality's 25 steps.

• Smaller images render faster too: set the Empty Latent Image size to 1280×1600 (about half the pixels of the default).

✨ Features

✅ One CONTROL PANEL, top-left — MODE, subject source, upscale switch, seed. Everything else is "Engine — no need to touch"

✅ 4 MODEs — 1 Dressed to Kill (fully dressed) · 2 Lace & Heat (lingerie / swimwear) · 3 Top Off (topless) · 4 Nothing But Skin (full nude). Clothing guards are built in

✅ Random from the built-in list, or "My own idea" — type your own scene line; the expander and guards still apply

✅ FAST switch (new in v1.1) — 0 Quality (25 steps, default, no LoRA) · 1 Fast (fewer steps, still no LoRA).

✅ BEAUTY switch (new in v1.1) — 0 Natural (default) · 1 Beauty (adds one line to the expander for a more polished, clearly adult look)

✅ Auto-prompt expander inside the graph — Qwen3-VL 8B (same file as the text encoder, no extra download)

✅ Hands-friendly prompt wording — simple hand anchors, no finger descriptions

✅ Optional Upscale — SeedVR2 2× (1792×2240 → 2560×3200), OFF by default

✅ Empty "Optional LoRA" slot — bypassed; drop in your own LoRA if you want one

✅ Civitai metadata embedded — model hash, prompt, seed, sampler in every PNG (Image Saver)

✅ No external files — all 4 subject lists are inside the workflow

🚀 How to Use

1. Download the 3 model files into the folders above. The loaders already use these exact file names.

2. In the CONTROL PANEL pick MODE: 1 Dressed to Kill · 2 Lace & Heat · 3 Top Off · 4 Nothing But Skin.

3. Press Queue. A new random image is made every run.

Optional:

• Subject source = 2 and type a scene in "My own idea" (for example: full body, red satin dress, rooftop bar at golden hour)

• Upscale: tick it in the switch on the left

• Several images: raise Batch count next to the Queue button

• Person box: the default is "Korean woman in her mid 20s" — change it to any adult woman you like

• FAST: 0 Quality (default) · 1 Fast (fewer steps, no download needed).

• BEAUTY: 0 Natural (default) · 1 Beauty — no extra download

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚙️ Settings & Parameters

• Size: 1792×2240 (4:5 portrait) · Sampler: euler / simple · Steps: 25 · CFG: 1.0

• Seed: randomize each run (switch to "fixed" in the Seed node to repeat an image)

• Expander: Qwen3-VL 8B, temperature 0.7, max 400 tokens, plus 3 small clean-up steps

• Output: PNG with Civitai metadata, saved to ComfyUI/output/qwen21_afterdark/<mode>/

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

💡 Performance Tips

• Base image 1792×2240: about 70 s on an RTX 5080 16 GB (first run is slower while models load). Upscale adds about 25 s.

• Upscale is OFF by default so first runs work on 16 GB VRAM / 32 GB RAM. The 7B upscale model needs about 48 GB RAM; if you turn it on with less, use the 3B model.

• Pairs well with "Qwen Image 2.1 Fix v1.0" by Envy (optional, not included, not needed): https://civarchive.com/models/2957332

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📋 Version History

• v1.0 — first release: 4-mode auto-prompt workflow, one control panel, no LoRA needed.

• v1.1 — adds two panel switches: FAST (0 Quality, 25 steps, no LoRA, about 68 s · 1 Fast, 16 steps, no LoRA, about 40 s) and BEAUTY (0 Natural · 1 Beauty, adds a polished-look line to the prompt, about 70 s, same cost as Quality). Resolution is 1792×2240 at every FAST level. Defaults unchanged (FAST=0, BEAUTY=0 render identically to v1.0). Tested at 100% crop: 30/32 Fast renders were clean at 16 steps; 2/32 (both MODE1 test seeds) showed occasional ghosting/doubling on a limb or edge, absent at Quality for the same seeds — use Quality if you need a guaranteed-clean result. Beauty read as more polished and clearly adult in all 16 cases.

📝 Notes & AI Disclosure

• All images are AI-generated with Qwen-Image 2.1 and show fictional adult women (mid 20s) — no real person is depicted.

• Adults only: keep the Person text an adult, and never edit the prompts or lists toward minors or real people.

• Clothing guards are prompt-based: check every image before you post it. Discard anything unclear, cropped or with wrong anatomy.

• Post nudity only where the platform allows it, and set the content rating correctly.
