# Reference ControlNet 🛂🅐🅒🅝
## Documentation
- Class name: `ACN_ReferenceControlNet`
- Category: `Adv-ControlNet 🛂🅐🅒🅝/Reference`
- Output node: `False`

The ACN_ReferenceControlNet node is designed to load and apply a Reference ControlNet configuration for advanced control in generative models. It allows for the customization of reference types, style fidelity, and reference weight to fine-tune the influence of the control net on the generative process.
## Input types
### Required
- **`reference_type`**
    - Specifies the type of reference to be used, affecting how the control net interprets and applies style and content guidance.
    - Comfy dtype: `COMBO[STRING]`
    - Python dtype: `str`
- **`style_fidelity`**
    - Determines the fidelity of the style to be applied by the control net, influencing the balance between style and content in the generated output.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`ref_weight`**
    - Controls the weight of the reference in the control net's decision-making process, adjusting the overall impact of the reference on the output.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
## Output types
- **`control_net`**
    - Comfy dtype: `CONTROL_NET`
    - The configured Reference ControlNet, ready to be applied to the generative model for influencing its output.
    - Python dtype: `ReferenceAdvanced`
## Usage tips
- Infra type: `CPU`
- Common nodes: unknown
