Transparent PNGs straight out of Krea 2 Turbo in 8 steps. End your prompt with <code>isolated on a transparent background</code>, decode with the two Wan-Alpha VAEs, and you get an image with a real alpha channel: no chroma key, no background removal, no masking, and no colored fringe on the edges. Only built-in ComfyUI nodes.Trained with black-and-white manga in mind (characters, creatures, props, ink effects, sound effects, speech balloons), but it also works in color.Everything you need (ComfyUI): <a target="_blank" rel="ugc" href="https://huggingface.co/paralaif/Krea2-Manga-Alpha-Image-LoRA">https://huggingface.co/paralaif/Krea2-Manga-Alpha-Image-LoRA</a>1.

Minimal workflow: the attached zip (also on Hugging Face)4. Krea 2 Turbo + Qwen3-VL-4B text encoder: Comfy-Org/Krea-2 on Hugging FaceHow it works: Krea 2 shares the Wan 2.1 latent space. Wan-Alpha extends that space with alpha (one fused latent, two decoders), and this LoRA teaches Krea 2 to generate that fused latent directly.Tips- Always end the prompt with <code>isolated on a transparent background</code>, and describe one subject, not a place.- About 1 in 5 prompts needs another seed; the failure is an obvious opaque pale-gray background.- Dense black masses (a flock of crows) are the weak spot.- Tuned for Krea 2 Turbo; on heavy fine-tunes like Kroma the alpha breaks.Training: Krea 2 Raw, musubi-tuner, latents encoded with the Wan-Alpha v2 encoder, 503 RGBA images, rank 32, AdamW 8-bit 1e-4, krea2_shift, epoch 4 (2012 steps), one RTX 5060 Ti 16 GB. The training images are synthetic: generated with MossAD-Demo using its built-in artist-style tags, on a flat indigo background, cut out with a chroma key and reviewed by hand. The artist tags were removed from the captions, but the LoRA may still carry some of those styles.License: Krea 2 Community License Agreement (included in the zip; <a target="_blank" rel="ugc" href="https://krea.ai/krea-2-licensing">https://krea.ai/krea-2-licensing</a>).

Krea 2 Manga Alpha Image LoRA

LoRA strength 1.0. Krea 2 Turbo: 8 steps, CFG 1, euler / simple. 832×1216, 1216×832 and 1024² tested. Only built-in ComfyUI nodes.Decode twice with the Wan-Alpha VAEs (color + alpha, both in the Hugging Face repo) and join them with ImageToMask → InvertMask → JoinImageWithAlpha. The attached workflow does it for you.
