# ConditioningSetMask - ComfyUI Built-in Node Documentation

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

This node is designed to modify the conditioning of a generative model by applying a mask with a specified strength to certain areas. It allows for targeted adjustments within the conditioning, enabling more precise control over the generation process.

## Inputs

### Required

| Parameter       | Description                                                                                                                                            | Data Type      |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | -------------- |
| `CONDITIONING`  | The conditioning data to be modified. It serves as the basis for applying the mask and strength adjustments.                                           | CONDITIONING   |
| `mask`          | A mask tensor that specifies the areas within the conditioning to be modified.                                                                         | `MASK`         |
| `strength`      | The strength of the mask's effect on the conditioning, allowing for fine-tuning of the applied modifications.                                          | `FLOAT`        |
| `set_cond_area` | Determines whether the mask's effect is applied to the default area or bounded by the mask itself, offering flexibility in targeting specific regions. | COMBO\[STRING] |

## Outputs

| Parameter      | Description                                                                     | Data Type    |
| -------------- | ------------------------------------------------------------------------------- | ------------ |
| `CONDITIONING` | The modified conditioning data, with the mask and strength adjustments applied. | CONDITIONING |
