Flux Green Screen Outpainting — FLUX.2-klein-4B LoRA (mirror)

A rank-16 edit LoRA for FLUX.2-klein-4B that extends an image by filling green border areas with contextually appropriate AI-generated content. Add a green border (or green regions) to an image and the model outpaints the scene into them naturally.
