SCAIL-2 GGUFs (by Rebel AI)

⚡ Load with the GGUF Unet Loader (city96's ComfyUI-GGUF — Unet Loader (GGUF)). Place the .gguf in ComfyUI/models/unet/.

Quant tiers

The loader memory-maps the model, so a larger file costs disk and streaming time, not resident RAM.

Required files (NOT included in this repo)

📝 Text Encoder

🎛️ LoRA (LightX2V step/cfg distill)

🎯 SAM 3.1 Multiplex

👁️ CLIP Vision

🎨 VAE

➕ Optional: SCAIL-2 DPO LoRA (untested)

Notes

• WEIGHT NOT MERGED warning on patch_embedding is harmless. ComfyUI builds a 36-channel patch embedding and concatenates the mask channels at runtime; the model fills them internally. The stored 20-channel weight is expected. Generation proceeds normally.
• The colored mask is a required input even in single-character Animation Mode — don't remove it from the workflow.
• Set width and height explicitly (both divisible by 16; 832×480 is a good 480p start).
• The SCAIL2ColoredMask node may require a recent / nightly ComfyUI build.
