BatchIndexCounter

Helper node to manage and increment batch index for checkpoint rotation. This node helps track the current position in batch generation, making it easier to use with CheckpointRotation node.

CheckpointFilename

Creates a filename that includes checkpoint information. Connect the checkpoint_name output from rotation node to this, then connect this to SaveImage's filename_prefix.

CheckpointRotation

A custom ComfyUI node that rotates through checkpoints based on batch generation count. This node allows automatic switching between different model checkpoints during batch image generation, enabling diverse outputs from multiple models.

CheckpointRotationSimple

Simplified checkpoint rotation that takes a direct checkpoint index. Setup: 1. Add this node 2. Set subfolder 3. Add a Primitive INT for checkpoint_index 4. Double-click LEFT side of primitive 5. Set control_after_generate to "increment" 6. Connect primitive to checkpoint_index input This forces the checkpoint to change based on the index value. For "change every N images", use increment step = 1 and this formula: actual_checkpoint = (index // N) % num_checkpoints

CheckpointRotationWithCounter

Checkpoint rotation that works with batch generation. How to use: 1. Add this node 2. Set subfolder and change_every 3. Right-click the 'counter' input -> Convert to input 4. Add a Primitive INT node 5. Connect Primitive INT to counter input 6. IMPORTANT: Double-click the LEFT SIDE of the Primitive node 7. Set "control_after_generate" to "increment" 8. Now when you generate with batch_size > 1, counter increments after each image 9. Checkpoint changes every N images based on change_every setting
