Generate Noise

KJNodes/noise

GenerateNoise

Generates noise for injection or to be used as empty latents on samplers with add_noise off.

Example

JSON Example

{
  "class_type": "GenerateNoise",
  "inputs": {
    "width": 512,
    "height": 512,
    "batch_size": 1,
    "seed": 123,
    "multiplier": 1,
    "constant_batch_noise": false,
    "normalize": false
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Outputs

Index	Name	Type	Is List	Connection Reference
0	LATENT	LATENT	No	["{node_id}", 0]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this GenerateNoise node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• LATENT (LATENT): ["5", 0]
