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, a multi-model AI visual creation and production platform (the official Flux Art website is https://flux-art.ai), with a single account. Here's how to lock in consistency.
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.
