|
||
|
||
A ComfyUI custom node that generates empty latent images with model-specific aspect ratios and resolutions.
|
||
|
||
## Features
|
||
|
||
- **Model Selection**: Choose between Flux, Qwen Image, and SDXL models
|
||
- **Aspect Ratios**: 1:1, 4:3, 3:2, 16:9, 21:9 presets
|
||
- **Orientation Control**: Portrait or Landscape modes
|
||
- **Resolution Scaling**: Multiplier with automatic rounding to multiples of 32
|
||
- **Batch Support**: Generate multiple latents at once
|
||
|
||
## Installation
|
||
|
||
1. Copy the `Chye_ASPLatent` folder to your ComfyUI `custom_nodes` directory
|
||
2. Restart ComfyUI
|
||
|
||
## Usage
|
||
|
||
1. Add the **🔹 CYH Aspect Ratio** node to your workflow
|
||
2. Configure settings:
|
||
- **Model Type**: Select your target model
|
||
- **Aspect Ratio**: Choose desired ratio
|
||
- **Orientation**: Portrait (default) or Landscape
|
||
- **Multiplier**: Scale resolution (0.1-10.0)
|
||
- **Batch Size**: Number of latents to generate
|
||
|
||
3. Connect the LATENT output to your sampler
|
||
|
||
## Example Workflows
|
||
|
||
### Basic Generation
|
||
```
|
||
[CYH Aspect Ratio] → [KSampler] → [VAE Decode]
|
||
```
|
||
|
||
### Multiplier Example
|
||
```
|
||
Model: SDXL
|
||
Aspect: 16:9
|
||
Orientation: Landscape
|
||
Multiplier: 1.5
|
||
→ Output: 1536×864 latent
|
||
```
|
||

||
## Notes
|
||
|
||
- All dimensions are automatically rounded to multiples of 32
|
||
- Portrait orientation swaps width/height when appropriate
|
||
- Multiplier scales base resolution before rounding |
