Building a text-to-image workflow in ComfyUI
ComfyUIDemo summary
The video shows how to connect a Load Checkpoint node to a KSampler, CLIP Text Encoders for positive/negative prompts, and a VAE Decode node to create a functional image generation pipeline.
Step-by-step
- Click and drag from the Model output of a Load Checkpoint node to the canvas.
- Select the KSampler node from the suggested menu to connect it.
- Drag from the CLIP output to create a CLIP Text Encode node for the positive prompt.
- Hold the ALT key and drag the CLIP Text Encode node to duplicate it for the negative prompt.
- Connect the positive and negative CLIP nodes to the corresponding inputs on the KSampler.
- Drag from the Latent input on the KSampler and select Empty Latent Image.
- Connect the VAE output from the Load Checkpoint node to a VAE Decode node.
- Connect the KSampler output to the VAE Decode node.
- Drag from the VAE Decode output and select Preview Image to view the result.
Options
- Hold Shift while dragging a noodle to access the full node menu instead of filtered suggestions.
- Use a Save Image node instead of Preview Image if you want to store the file on your computer.
Watch out for
- All inputs on the KSampler must be filled for the workflow to function.
- Negative prompts like 'bad anatomy' may not be very effective when using the base Stable Diffusion model.
Tips
- Use the ALT + drag shortcut to quickly duplicate existing nodes.
- Stick to the default 512x512 resolution for the Empty Latent Image as that is what the base model was trained on.
