ControlNet strength advisor
The two settings that make or break a ControlNet generation are the control weight and the guidance window (start % and end %). Too strong and the output is a stiff trace of your reference; too weak and the structure you wanted is ignored. This advisor turns “I want the pose but a totally different scene” into concrete numbers you can paste into A1111, ComfyUI or Forge.
How the recommendation is built
Each control type has a baseline weight reflecting how strict its map is — OpenPose and Canny grip hard, Scribble and Reference are gentle. Your freedom slider then shifts three things at once:
- Weight drops as you ask for more freedom (a looser grip on structure).
- Start % moves later, so the first noisy steps are unconstrained and the model can reinterpret the layout.
- End % moves earlier, handing the final detail steps back to the prompt.
The result is a balanced trio rather than a single number, because when the control is active matters as much as how hard.
Tips
- For faithful product or architectural renders, keep freedom low so the control runs the full schedule (0% → 100%).
- For character work, lock the pose but end control around 70–80% so faces and clothing get realistic detail in the late steps.
- If you see ghosting or doubled edges, your weight is too high — lower it by 0.2 before touching anything else.
