# ZImageFunControlnet - ComfyUI Built-in Node Documentation

> Complete documentation for the ZImageFunControlnet node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ZImageFunControlnet node applies a specialized control network to influence the image generation or editing process. It uses a base model, a model patch, and a VAE, allowing you to adjust the strength of the control effect. This node can work with a base image, an inpainting image, and a mask for more targeted edits.

## Inputs

| Parameter       | Description                                                                                                                            | Data Type    | Required | Range         |
| --------------- | -------------------------------------------------------------------------------------------------------------------------------------- | ------------ | -------- | ------------- |
| `model`         | The base model used for the generation process.                                                                                        | MODEL        | Yes      | -             |
| `model_patch`   | A specialized patch model that applies the control network's guidance.                                                                 | MODEL\_PATCH | Yes      | -             |
| `vae`           | The Variational Autoencoder used for encoding and decoding images.                                                                     | VAE          | Yes      | -             |
| `strength`      | The strength of the control network's influence. Positive values apply the effect, while negative values can invert it (default: 1.0). | FLOAT        | Yes      | -10.0 to 10.0 |
| `image`         | An optional base image to guide the generation process.                                                                                | IMAGE        | No       | -             |
| `inpaint_image` | An optional image used specifically for inpainting areas defined by a mask.                                                            | IMAGE        | No       | -             |
| `mask`          | An optional mask that defines which areas of an image should be edited or inpainted.                                                   | MASK         | No       | -             |

**Note:** The `inpaint_image` parameter is typically used in conjunction with a `mask` to specify the content for inpainting. The node's behavior may change based on which optional inputs are provided (e.g., using `image` for guidance or using `image`, `mask`, and `inpaint_image` for inpainting).

## Outputs

| Output Name | Description                                                                             | Data Type    |
| ----------- | --------------------------------------------------------------------------------------- | ------------ |
| `model`     | The model with the control network patch applied, ready for use in a sampling pipeline. | MODEL        |
| `positive`  | The positive conditioning, potentially modified by the control network inputs.          | CONDITIONING |
| `negative`  | The negative conditioning, potentially modified by the control network inputs.          | CONDITIONING |
