ComfyUI
- Download & unzip ComfyUI-UMT5-Extended/ ->
ComfyUI/custom_nodes/ encoders/*.safetensors->ComfyUI/models/text_encoders/UMT5_extended/- Restart ComfyUI
- CLIP Loader -> wan ->
nsfw_wan_umt5_xxl_v2_fp16.safetensors(or fp8)
Custom node: ComfyUI hardcodes vocab_size: 256384. Extended files need 257067. The node sets this from shared.weight shape automatically.
Manual (no node): edit comfy/text_encoders/umt5_config_xxl.json -> "vocab_size": 257067 (revert to 256384 for stock encoders).
Not using ComfyUI
No custom node. You need vocab_size=257067 and the extended tokenizer.
pip install torch safetensors transformers
python load_example.py
