Start with ControlNet by inspecting the control image before the output
Identify the expected edge, pose or depth representation and trace how its conditioning reaches the sampler. Different control models are not one universal node.
Purpose and scope
Identify the expected edge, pose or depth representation and trace how its conditioning reaches the sampler. Different control models are not one universal node.
Source-supported context
Official instructions pair control types with specific input images and do not include every preprocessor in the core. A preprocessed example does not mean any photograph is a direct replacement. Source 1
Before you start
1. Use a matched base/ControlNet family and a minimal reference workflow.
2. When preprocessing is required, identify its node and assets from a clear source.
3. Begin with one control input and no additional complex adapters.
Steps and checks
The sequence below is an editorial procedure based on the cited context, not a diagnosis already confirmed for your environment.
Step 1. Choose one control target, prepare the representation requested by the author and inspect its preview.
Step 2. Load the matching weights, connect image and control model to the apply node, then connect its output to the actual conditioning path.
Step 3. Establish a baseline with the example's strength/timing and compare control on/off while keeping other parameters fixed.
Step 4. For weak effects, inspect image type and links first. For computation errors, check model structure and versions instead of maximizing strength.
Completion check
The input matches the documented representation, conditioning is connected and output differences are explainable.
Limitations and cautions
Multiple controls can compete. Pose or edge input is not a pixel-exact reproduction guarantee; preprocessing and model limitations still matter.
