Workflow Goal
Provide a clean reference implementation for identity swapping using the Krea2 Identity Edit LoRA.
This workflow demonstrates how Krea2 Identity Edit can be used with two reference images to transfer a character identity into a source scene while preserving the source pose, composition, and overall scene structure.
The source image provides the Scene / Pose.
The second image provides the Character reference.
The edit instruction can optionally specify additional changes.
Treat this workflow as a starting point and adapt the reference images and edit instructions to suit your own creative workflow.
Workflow Philosophy
FisherKing Reference Workflows are intentionally minimal. They focus on demonstrating a validated baseline rather than exposing every possible option. Once the baseline is understood, users are encouraged to extend the workflow to suit their own production pipelines.
Workflow Type
Image-to-Image (Identity Swap using Krea2 Identity Edit)
This workflow uses the Krea2 Identity Edit LoRA together with the ComfyUI-Krea2Edit custom nodes.
Unlike traditional Image-to-Image workflows that rely primarily on denoising strength, Krea2 Identity Edit uses a reference-guided editing pipeline.
In this implementation, two images are supplied:
• Scene / Pose — provides the source composition, pose, and scene structure
• Character — provides the identity and visual characteristics to be transferred
The identity transfer is established through the reference-guided image conditioning and does not need to be explicitly described in the edit prompt.
Krea2 Identity Edit can simultaneously apply natural-language edit instructions alongside the identity transfer.
About this Workflow
The goal of this reference workflow is to provide a simple, educational implementation of the two-image identity-transfer capability of Krea2 Identity Edit.
Typical use cases include:
✓ Character identity swapping
✓ Transferring a character into an existing pose
✓ Character re-staging
✓ Clothing and color modifications
✓ Object addition and removal
✓ Additional instruction-based image edits
Prompting
The Scene / Pose and Character reference images establish the identity-transfer relationship.
Therefore, the prompt does not need to explicitly instruct Krea2 Identity Edit to replace or swap the character.
The prompt can instead focus on any additional changes required in the final image.
For example:
Change the skirt color to yellow. Change the shirt color to rose.
Additional edit instructions can be added as required.
Keeping the prompt focused on the desired edits provides a simple starting point for experimentation.
Observed Behavior
During validation, the workflow produced:
✓ Strong pose retention
✓ Strong source composition retention
✓ Effective character identity transfer
✓ Good transfer of distinctive character characteristics
✓ Good prompt adherence for straightforward edits
✓ Successful identity transfer combined with additional image editing
Pose and source composition were generally retained reliably across validation runs.
Edit fidelity varied depending on the complexity of the requested changes, reference images, and random seed.
More complex multi-part edits may require several generations to achieve the desired result.
Reference Compatibility
Identity transfer worked well across a variety of characters and substantially different source poses during validation.
One observed factor that may affect consistency is transferring a short-haired character onto a Scene / Pose image containing long hair. In some cases, characteristics of the source hair may persist or influence the resulting image.
This does not prevent the identity transfer from working, but additional generations or prompt guidance may be required to obtain the desired result.
Significant pose differences between the Scene / Pose and Character references were handled well during validation.
Results May Vary Depending On
• Source Scene / Pose image
• Character reference image
• Reference compatibility
• Edit instruction
• Edit complexity
• Random seed
• Reference image quality
• ref_boost setting
If the desired result is not achieved on the first attempt, consider:
• Refining or simplifying the edit instruction
• Trying a different random seed
• Using a more compatible character reference where appropriate
• Adjusting the ref_boost value
• Regenerating the image
