A Guide to FLUX.2-dev-Fun-Controlnet-Union
Overview
FLUX.2-dev-Fun-Controlnet-Union is a ControlNet adapter for FLUX.2-dev that enables precise spatial control over image generation through multiple condition types including Canny edge detection, HED edge maps, depth maps, pose skeletons, MLSD line detection, scribble input, and grayscale images. Built by alibaba-pai, this model adds control mechanisms to 4 double blocks within the FLUX.2-dev architecture and includes inpainting capabilities. The critical distinction from FLUX.2-dev's native editing features is that this ControlNet reliably follows control instructions across multiple control types simultaneously without the speed degradation or similarity issues that plague the base model's editing mode. The model comes in two variants: the newer 2602 version with added Scribble and Gray controls plus CFG distillation for improved generation quality, and the original version supporting Canny, HED, Depth, Pose, and MLSD controls. Implementation requires the VideoX-Fun library and the base FLUX.2-dev model weights. The controlnet_conditioning_scale parameter operates optimally in the 0.65 to 0.80...
