Generate a character concept

infsh app run falai/flux-dev-lora --input '{ "prompt": "character design reference sheet, front view of a young woman with short red hair, green eyes, wearing a blue jacket and white t-shirt, full body, white background, clean lines, concept art style, character turnaround", "width": 1024, "height": 1024 }' The Consistency Problem AI image generation produces different-looking characters every time, even with the same prompt. This is the #1 challenge in AI art for any project requiring the same character across multiple images. Solutions (Ranked by Effectiveness) Technique Consistency Effort Best For FLUX LoRA (trained on character) Very high High (requires training data) Ongoing projects, many images Detailed description anchor Medium-high Low Quick projects, few images Same seed + similar prompt Medium Low Variations of single pose Image-to-image refinement Medium Medium Refining existing images Reference image in prompt Varies Low When model supports it Reference Sheet Types 1. Turnaround Sheet Shows the character from multiple angles: ┌────────┬────────┬────────┬────────┐ │ │ │ │ │ │ FRONT │ 3/4 │ SIDE │ BACK │ │ VIEW │ VIEW │ VIEW │ VIEW │ │ │ │ │ │ └────────┴────────┴────────┴────────┘

Generate front view

infsh app run falai/flux-dev-lora --input '{ "prompt": "character design, front view, young woman with short asymmetric red hair, bright green eyes, wearing navy blue bomber jacket over white graphic tee, dark jeans, red sneakers, standing in neutral pose, full body, clean white background, concept art, sharp details", "width": 768, "height": 1024 }' --no-wait

Generate 3/4 view (same description)

infsh app run falai/flux-dev-lora --input '{ "prompt": "character design, three-quarter view, young woman with short asymmetric red hair, bright green eyes, wearing navy blue bomber jacket over white graphic tee, dark jeans, red sneakers, standing, full body, clean white background, concept art, sharp details", "width": 768, "height": 1024 }' --no-wait

Generate side view

infsh app run falai/flux-dev-lora --input '{ "prompt": "character design, side profile view, young woman with short asymmetric red hair, bright green eyes, wearing navy blue bomber jacket over white graphic tee, dark jeans, red sneakers, standing, full body, clean white background, concept art, sharp details", "width": 768, "height": 1024 }' --no-wait

Generate back view

infsh app run falai/flux-dev-lora --input '{ "prompt": "character design, back view, young woman with short asymmetric red hair, wearing navy blue bomber jacket over white graphic tee, dark jeans, red sneakers, standing, full body, clean white background, concept art, sharp details", "width": 768, "height": 1024 }' --no-wait

Stitch into reference sheet

infsh app run infsh/stitch-images --input '{ "images": ["front.png", "three-quarter.png", "side.png", "back.png"], "direction": "horizontal" }' 2. Expression Sheet Shows the character's face with different emotions: ┌────────┬────────┬────────┐ │NEUTRAL │ HAPPY │ ANGRY │ │ │ │ │ ├────────┼────────┼────────┤ │ SAD │SURPRISE│THINKING│ │ │ │ │ └────────┴────────┴────────┘ Minimum 6 expressions: neutral, happy, angry, sad, surprised, thinking.

Neutral

infsh app run falai/flux-dev-lora --input '{ "prompt": "character portrait, close-up face, young woman with short red hair and green eyes, neutral calm expression, clean white background, concept art, consistent character design", "width": 512, "height": 512 }' --no-wait

Happy

infsh app run falai/flux-dev-lora --input '{ "prompt": "character portrait, close-up face, young woman with short red hair and green eyes, warm genuine smile, happy expression, clean white background, concept art, consistent character design", "width": 512, "height": 512 }' --no-wait

Angry

infsh app run falai/flux-dev-lora --input '{ "prompt": "character portrait, close-up face, young woman with short red hair and green eyes, furrowed brows, angry determined expression, clean white background, concept art, consistent character design", "width": 512, "height": 512 }' --no-wait

(Continue for sad, surprised, thinking...)

Outfit/Costume Sheet Multiple outfits for the same character: Outfit Description Casual Bomber jacket, t-shirt, jeans Work Blazer, button-down, slacks Athletic Sports bra, leggings, running shoes Formal Evening dress, heels
Color Palette Sheet Document exact colors for consistency: CHARACTER: Maya Chen Skin: ████ #F5D0A9 (warm beige) Hair: ████ #C0392B (auburn red) Eyes: ████ #27AE60 (emerald green) Jacket: ████ #2C3E50 (navy blue) T-shirt: ████ #ECF0F1 (off-white) Jeans: ████ #34495E (dark slate) Shoes: ████ #E74C3C (bright red) The Description Anchor Technique The most practical consistency technique: write a 50+ word detailed description and reuse it exactly in every prompt. Template [age] [gender] with [hair: color, length, style], [eye color] eyes, [skin tone], [facial features: any distinctive marks], wearing [top: specific color and style], [bottom: specific color and style], [shoes: specific color and style], [accessories: specific items] Example young woman in her mid-twenties with short asymmetric auburn red hair swept to the right side, bright emerald green eyes, light warm skin with a small beauty mark below her left eye, wearing a fitted navy blue bomber jacket with silver zipper over a white crew-neck t-shirt, dark slate slim jeans, and bright red canvas sneakers, small silver stud earrings Use this exact block in EVERY prompt for this character, only changing the action/pose/scene. Proportion Guide Style Head-to-Body Ratio Best For Realistic 7.5 : 1 Film, photorealistic Heroic 8 : 1 Superheroes, action Anime/Manga 5-6 : 1 Japanese animation style Stylized 4-5 : 1 Western animation Chibi/Super-deformed 2-3 : 1 Cute, comedic, mascots Include proportion style in your prompts: "realistic proportions" vs "anime style proportions" vs "chibi proportions" Using LoRA for Consistency For projects requiring many images of the same character, train a LoRA:

Use FLUX with a character LoRA

infsh app run falai/flux-dev-lora --input '{ "prompt": "maya_chen character, sitting at a cafe reading a book, warm afternoon light, candid photography style", "loras": [{"path": "path/to/maya-chen-lora.safetensors", "scale": 0.8}] }' LoRA Training Tips: Need 10-20 reference images of the character (consistent style) Train on specific trigger word (e.g., "maya_chen") Scale 0.7-0.9 balances consistency with prompt flexibility Lower scale = more creative freedom, higher = more strict matching Common Consistency Failures Issue Why It Happens Mitigation Hair color drift Model interprets "red hair" differently each time Use specific shade: "auburn red #C0392B" Eye color change Low priority in generation Mention eye color early in prompt Outfit inconsistency Model fills in details creatively Describe every clothing item explicitly Age shift Vague age description Use "mid-twenties" not "young" Face structure change Different generations = different faces Use LoRA or same seed base Proportion shift Style interpretation varies Specify "7.5 head proportions" Character Bible Template For ongoing projects, maintain a character bible document:

LoRA (if trained) Path: ./loras/maya-chen-v2.safetensors Trigger: maya_chen Recommended scale: 0.8 Common Mistakes Mistake Problem Fix Vague descriptions Different character every time 50+ word detailed anchor Inconsistent prompt structure Varying emphasis = varying results Same structure, only change action/scene Generating one view only Can't use character in different contexts Create full turnaround reference No color documentation Colors drift across generations Record exact hex codes Skipping expression sheet Character feels one-dimensional Generate 6+ expressions Not using LoRA for big projects Inconsistency compounds Train LoRA for 10+ image projects
