Leave this blank to use the worker's default. Lower values generally give the map less influence; higher values generally give it more. Excessive strength can distort colours or shapes.There is no single useful threshold for every detector or picture. Compare values with the same source, prompt, model, and seed. Inspect the control map too: increasing strength cannot recover features the detector missed.The examples were made on local worker software, one set per detector.The studio accepts 0.01 to 3 with ControlNet or the QR code workflow. Setting an explicit strength requires a worker that supports the field, which may reduce the eligible pool.
The examples on this page were made from one prompt, one model and one seed, changing only the setting shown. Other pictures, models and settings respond differently; compare on your own request with the seed and the other settings fixed.
