Transparent PNGs straight out of MOSS-Image. End your prompt with <code>isolated on a transparent background</code>, decode with the RGBA VAE, and the sampler gives you an image with a real alpha channel: no chroma key, no background removal, no masking.Trained with black-and-white manga in mind (characters, creatures, props, ink effects, sound effects, speech balloons), but it also works in color.<h3 id="everything-you-need-(comfyui)">Everything you need (ComfyUI)</h3>Files, raw RGBA examples, trailer and full notes: <a target="_blank" rel="ugc" href="https://huggingface.co/paralaif/MOSS-Manga-Alpha-Image-LoRA">huggingface.co/paralaif/MOSS-Manga-Alpha-Image-LoRA</a><ol><li>This LoRA → <code>models/loras/</code></li><li>RGBA VAE <code>vae/flux2_klein_alpha_rgba_vae.safetensors</code> (in the Hugging Face repo; originally trmz/flux2-klein-alpha, Apache-2.0) → <code>models/vae/</code></li><li>Load RGBA VAE (Flux2) custom node + minimal workflow: the attached zip (also on Hugging Face).
