Flux.2 Klein LoRA for 360° Panoramas + ComfyUI Panorama Stickers (interactive editor)

Independent developer 'nomadoor' has open-sourced a novel toolkit that transforms the Flux.2 Klein AI image model into a specialized 360° panorama generator. The project consists of two core components: custom-trained LoRAs (Low-Rank Adaptations) that teach the base model to understand equirectangular projection, and an interactive ComfyUI node that solves the major UX problem of placing 2D elements in a 360° space. Instead of a purely text-to-image approach, the system frames panorama creation as a controlled outpainting task. Users start with a blank 2:1 canvas, strategically place reference images, and let the AI fill the remaining 'green-screened' areas, offering unprecedented control over the final spherical composition.

The technical release includes two LoRA files (a 4B and a 9B parameter version) and the 'ComfyUI-Panorama-Stickers' node package. The editor node is the standout feature, allowing creators to enter a 3D preview of the panorama and place image 'stickers' in the exact desired direction, which are then compiled into a control map for generation. A secondary node can extract standard perspective 'photos' from any viewpoint within the generated panorama, making the outputs practical for traditional media. The developer notes limitations, including the need for the full Flux.2 Klein base model (not distilled versions), a recommended output of 2048x1024 resolution, and the ongoing challenge of seamless edge matching, which may require post-processing with upscaling or inpainting tools.
