Generating the same character consistently across multiple images is AI art's biggest challenge — and Midjourney's Character Reference feature is the solution.

Midjourney Character Reference (--cref)

• Provide a reference image of your character
• Midjourney maintains their appearance across new scenes
• --cref [image URL] --cw 100 (cw = character weight, 0–100)

Other Methods

• Stable Diffusion + LoRA fine-tuning — most consistent for product/brand characters
• DALL-E 3: Describe the character in extreme detail every time
• Consistent seed values in Midjourney (partial consistency)
