Nodes

Loop Nodes

True loop functionality without Auto Queue. Iterate through batches/lists and accumulate results in a single execution.

Loop Workflow

Loop Start 🪽

Start a loop over items.

| Input | Type | Description | |-------|------|-------------| | items | ANY | Batch/list to iterate over. Accepts IMAGE batch, lists of strings, or any iterable. |

| Output | Type | Description | |--------|------|-------------| | flow | FLOW_CONTROL | Must connect to Loop End. | | item | ANY | Current item from the batch for this iteration. |

Example - Loop through text prompts:

[Text Permutation] outputs: ["cat on chair", "cat on sofa", "dog on chair", "dog on sofa"]
         ↓
[Loop Start] iteration 0: item = "cat on chair"
[Loop Start] iteration 1: item = "cat on sofa"
[Loop Start] iteration 2: item = "dog on chair"
[Loop Start] iteration 3: item = "dog on sofa"

Loop End 🪽

End a loop and collect all results into a single output.

| Input | Type | Description | |-------|------|-------------| | flow | FLOW_CONTROL | Must connect from Loop Start. | | result1 | ANY | Value to collect from each iteration (optional). | | result2 | ANY | Second value to collect (optional). |

| Output | Type | Description | |--------|------|-------------| | results1 | ANY | All accumulated results from result1. | | results2 | ANY | All accumulated results from result2. |

v0.6.0: Loop End now executes even without downstream connections. You can run loops without connecting nodes to the results outputs.

Accumulation behavior:

IMAGE/MASK tensors: Concatenated into a batch tensor. 4 images → tensor shape (4, H, W, C)
Strings: Collected into a Python list.
Other types: Collected into a Python list.

Tips & Best Practices

Loop Performance

Image Bridge is essential - Without it, you won't see intermediate results
No downstream required - Loop End now runs even without connected outputs (v0.6.0)
Memory usage - Each iteration accumulates in memory. For large batches, use Split Image Batch with Auto Queue

Smart Composite Workflow

[Load Image] → [Image Bridge] → canvas [Smart Composite]
                                overlay ← [Load Logo]
                                mask ← [Load Logo].mask (with invert_mask: true)

Metadata Workflow

[Load Image + Metadata] → metadata_raw
         ↓
[Parameter Parser] → formatted, model, seed, etc.
         ↓
[Parameter Overlay] ← original image
         ↓
[Save Image]

Example Workflows
