Midjourney just rolled out Omni Reference in V7. This new feature lets you point to a reference image and tell Midjourney to put that specific character, object, or creature into your generated image.
For creatives needing practical, usable results with specific elements, this offers a major productivity boost beyond relying purely on text prompt randomness. It makes getting consistent characters or objects into your generations much more reliable.
You use the --oref parameter with an image link and adjust its influence with --ow (omni-weight), using your text prompt to guide the overall scene and any modifications. It works alongside other V7 features.
