New ComfyUI Node for Krea 2 Fixes Multi-Character LoRA Face Blending
tekprodfx16 · reddit · 2026-07-31
A developer has released a V12 ComfyUI custom node for the Krea 2 base model, effectively solving the notorious 'face blending' issue when using multiple character LoRAs in a single generation.
Key Features & Technical Highlights:
- Precise Regional Control: Assign LoRAs to specific bounding boxes. It uses a fused block-sparse FlexAttention mask to structurally prevent LoRA deltas from affecting pixels outside their designated box.
- Scene & Outfit Transfer: Drop LoRA characters into real photos with natural lighting and perspective integration. Also supports outfit or object transfer using a second reference image.
- Face-Anchored Detailer: An optional post-pass node that detects faces, assigns them to their correct regions by proximity, and re-renders them at high resolution with the accurate LoRA, restoring identity even if placement drifts.
