Overview
Configure the preprocessor for the model family, such as SDXL, and for the selected control type. Set its resolution to match the intended generation scale. A Preview Image node can be attached to the preprocessor output to inspect the actual control image before it influences the final generation.
Available control types include:
OpenPose: Converts a person into a pose skeleton so generated characters follow the body arrangement.
Depth: Creates a depth map that can preserve spatial relationships, object placement, and relative distance.
Canny: Reduces an image to prominent edges so a new generation follows its major shapes.
Line Art: Uses drawn outlines as structural guidance.
Anime Line Art: A line-art option optimized for anime characters, including pose and clothing outlines.
Scribble: Uses simple drawn lines as a loose structural guide.
Segmentation: Divides the image into regions so complex scenes with multiple people and objects can preserve their approximate locations.
Strength controls the influence of the processed reference. A value of 0 means ControlNet has no effect. A value of 1 applies maximum influence. The pose example starts at 0.8; increasing it to 1 makes the final image follow the pose more completely.
