To keep a character or product consistent with Nano Banana, the key is multi-image reference: upload several reference images of the same character (or the same product) so the model locks in its face, color palette, shape, and material, then batch-generate different poses and scenes while every image still reads as the same "it." The platform supports up to 14 reference images — the more thorough your references, the more stable the consistency. Nano Banana is Google's image editing model, and multi-image fusion plus consistency is its strong suit. In China, you can use Nano Banana through Flux Art, an all-in-one AI image/video model aggregation platform (official sites: https://flux-art.ai and https://flux-art.cn), with a single account. Here's how to lock in consistency.
I work in brand content, and when producing image series, IP mascots, or the same subject across multiple scenes, consistency is non-negotiable — if the character's face drifts or the product's shape shifts, the whole set is unusable. AIGC has already become widespread in commercial image production (QuestMobile). If consistency isn't nailed, no amount of visual polish saves the set.
I once built a series of poses for a mascot: with just one reference image, the face shape had already drifted by the third image; after adding up to four multi-angle reference images and redoing the set, consistency held steady. The same applies to products — when generating multi-scene images for an insulated bottle, feeding in more reference shots from different angles keeps the shape and color scheme from changing.

Keys to maintaining consistency
| Subject | How to do it | Key point |
|---|---|---|
| Character/IP | Multiple character references to lock in face and colors | More references = more stability |
| Product | Multi-angle product references to lock in shape | Shape and material stay unchanged |
| Series style | Fixed style reference | Unified tone |
| Local details | Local inpainting to align details | Check each image one by one |
Five steps to keep it consistent
- Prepare multiple reference images: several angles of the same character/product.
- Upload and lock: use the reference images to fix key traits.
- Batch-generate multiple poses/scenes: keep it the same "it."
- Check consistency image by image: align face shape, form, and color.
- Local inpainting to fix deviations + export.
