Flux Kontext + PuLID + Detail Daemon — Character LoRA Dataset Generator (164+ images)

Running Kontext ReferenceLatent conditioning through standard PuLID throws an error about unexpected conditioning format. Fix: patch pulidflux.py to add timestep_zero_index kwarg support and generation-token-only injection mode. Full patch instructions in the linked Article. ━━━ HARDWARE REQUIREMENTS ━━━ • Minimum: 16GB VRAM (will be slow, may need to reduce steps/resolution) • Recommended: 24GB+ VRAM (RTX 3090/4090) • Ideal: 48–96GB VRAM (A100, H100, RTX 6000 Ada) • RAM: 32GB+ system RAM • Storage: ~22GB for all models + 5–10GB per batch run output ━━━ REQUIRED MODELS ━━━ Place in the specified ComfyUI subdirectory: • models/unet/ — flux1-dev-kontext_fp8_scaled.safetensors (~17GB) [HuggingFace: black-forest-labs] • models/vae/ — ae.safetensors (~335MB) [HuggingFace: black-forest-labs/FLUX.1-dev] • models/clip/ — clip_l.safetensors (~246MB) + t5xxl_fp8_e4m3fn_scaled.safetensors (~4.7GB) • models/loras/ — flux_realism_lora.safetensors (XLabs — CivitAI) • models/loras/ — fluxRealSkin_v2.safetensors (CivitAI) • models/pulid/ — pulid_flux_v0.9.0.safetensors InsightFace weights download automatically on first run (internet required for first execution only). ━━━ REQUIRED CUSTOM NODES ━━━ • ComfyUI-PuLID-Flux (with pulidflux.py patch — see Article) • ComfyUI-Detail-Daemon • ComfyUI-Kontext (ReferenceLatent + FluxKontextImageScale — built into recent ComfyUI) ━━━ TO USE ━━━ 1. Place 3 reference images in ComfyUI/input/: — Node 4: full/3-quarter body reference — Node 30: head+shoulders face reference — Node 20: tight face crop for PuLID (face fills 70%+ of frame, near-frontal angle) 2. Edit CLIPTextEncode (Node 7) with your character description 3. Run a single image first to verify setup, then queue the full batch ━━━ KEY PARAMETERS ━━━ PuLID — Node 24: weight 0.73 (0.35–0.75 useful range) — higher = stronger identity, lower = more variation start_at 0.05 — leave at 0.05; lets structure form before identity locks end_at 0.72 — lower if skin looks plastic; releases final texture passes from PuLID constraint Detail Daemon — Node 50: detail_amount 0.40 (0.20–0.55 range) — sweet spot; 0.50+ = over-sharpened start 0.25 / end 0.80 — active across mid-sampling where detail resolves LoRA strengths: XLabs Realism (Node 40): 0.60 (0.35–0.75 useful range) FluxRealSkin v2 (Node 41): 0.45 (0.25–0.55 useful range) Note: these two compound — if you raise one, slightly lower the other Sampling: 25 steps, euler_ancestral, simple scheduler, guidance 2.5 ━━━ FILES INCLUDED ━━━ • workflow_ui_format.json — import directly into ComfyUI Generates 164 photorealistic identity-consistent images from 3 reference photos. Built for high-quality synthetic training datasets for Wan 2.2 / HunyuanVideo character LoRAs — but outputs are also great standalone character content. Developed across 16 test iterations for maximum photorealism, identity consistency, and anatomical accuracy. ━━━ WHAT IT DOES ━━━ Combines three techniques that individually exist in the community but haven't been documented together in a single production-ready batch pipeline: • Flux Kontext DUAL reference chain — body ref + face ref simultaneously, stronger than single ref • PuLID Flux face identity injection — biometric-level face locking via InsightFace embeddings • Detail Daemon sampler augmentation — forces skin pores, hair strands, iris texture to resolve • XLabs Flux Realism LoRA + FluxRealSkin v2 stacked for photographic skin rendering ━━━ OUTPUT ━━━ 82 prompts × 2 seeds = 164 images: • 10 extreme close-ups (frontal, 90° profile left/right, dutch tilt, high angle, low angle, head down) • 15 portraits head+shoulders (laughing, looking away, over-shoulder, near-profile, editorial, candid) • 15 medium waist-up shots • 12 full body — 768×1152 PORTRAIT canvas so subjects look tall, not short • 12 revealing/fashion outfits • 12 lifestyle/candid • 6 lighting moods (golden hour, dramatic shadow, neon night, overcast, backlit, morning window) ━━━ KEY TECHNICAL FINDINGS ━━━ 1. PuLID must be applied AFTER LoRAs — LoRAs define rendering style first, PuLID locks face into it 2. Detail Daemon wraps the SAMPLER output of KSamplerSelect, NOT the sigmas — wrong wiring = 400 error 3. SamplerCustomAdvanced + BasicGuider is REQUIRED when using PuLID (standard KSampler won't work) 4. 768×1152 portrait canvas for full body — square 1024×1024 makes subjects look short/wide ━━━ COMPATIBILITY WARNING — READ BEFORE INSTALLING ━━━ The standard ComfyUI-PuLID-Flux node is NOT compatible with Flux Kontext out of the box.
