The SamplerEulerAncestralCFGPP node creates a specialized sampler for generating images using the Euler Ancestral method with classifier-free guidance. This sampler combines ancestral sampling techniques with guidance conditioning to produce diverse image variations while maintaining coherence. It allows fine-tuning of the sampling process through parameters that control noise and step size adjustments.

## Inputs

| Parameter | Data Type | Required | Range      | Description                                                                                                    |
| --------- | --------- | -------- | ---------- | -------------------------------------------------------------------------------------------------------------- |
| `eta`     | FLOAT     | Yes      | 0.0 - 1.0  | Controls the step size during sampling, with higher values resulting in more aggressive updates (default: 1.0) |
| `s_noise` | FLOAT     | Yes      | 0.0 - 10.0 | Adjusts the amount of noise added during the sampling process (default: 1.0)                                   |

## Outputs

| Output Name | Data Type | Description                                                                           |
| ----------- | --------- | ------------------------------------------------------------------------------------- |
| `sampler`   | SAMPLER   | Returns a configured sampler object that can be used in the image generation pipeline |
