Outputs

Index	Name	Type	Is List	Connection Reference
0	BASIC_PIPE	BASIC_PIPE	No	["{node_id}", 0]
1	LATENT	LATENT	No	["{node_id}", 1]
2	VAE	VAE	No	["{node_id}", 2]

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 ImpactKSamplerAdvancedBasicPipe node in your workflow, and output_index is the index from the table above.

Example

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

• BASIC_PIPE (BASIC_PIPE): ["5", 0]
• LATENT (LATENT): ["5", 1]
• VAE (VAE): ["5", 2]
