### 🔨Wan-Alpha Video Usage
|
|
|
|
1. Download models
|
|
- The Wan DiT base model: [wan2.1_t2v_14B_fp16.safetensors](https://huggingface.co/Comfy-Org/Wan_2.1_ComfyUI_repackaged/blob/main/split_files/diffusion_models/wan2.1_t2v_14B_fp16.safetensors)
|
|
- The Wan text encoder: [umt5_xxl_fp8_e4m3fn_scaled.safetensors](https://huggingface.co/Comfy-Org/Wan_2.1_ComfyUI_repackaged/blob/main/split_files/text_encoders/umt5_xxl_fp8_e4m3fn_scaled.safetensors)
|
|
- The LightX2V model: [lightx2v_T2V_14B_cfg_step_distill_v2_lora_rank64_bf16.safetensors](https://huggingface.co/Kijai/WanVideo_comfy/blob/main/Lightx2v/lightx2v_T2V_14B_cfg_step_distill_v2_lora_rank64_bf16.safetensors)
|
|
- RGBA Dora: [epoch-13-1500_changed.safetensors](https://huggingface.co/htdong/Wan-Alpha_ComfyUI/blob/main/epoch-13-1500_changed.safetensors)
|
|
- RGB VAE Decoder: [wan_alpha_2.1_vae_rgb_channel.safetensors.safetensors](https://huggingface.co/htdong/Wan-Alpha_ComfyUI/blob/main/wan_alpha_2.1_vae_rgb_channel.safetensors.safetensors)
|
|
- Alpha VAE Decoder: [wan_alpha_2.1_vae_alpha_channel.safetensors.safetensors](https://huggingface.co/htdong/Wan-Alpha_ComfyUI/blob/main/wan_alpha_2.1_vae_alpha_channel.safetensors.safetensors)
|
|
|
|
2. Copy the files into the `ComfyUI/models` folder and organize them as follows:
|
|
|
|
```
|
|
ComfyUI/models
|
|
├── diffusion_models
|
|
│ └── wan2.1_t2v_14B_fp16.safetensors
|
|
├── loras
|
|
│ ├── epoch-13-1500_changed.safetensors
|
|
│ └── lightx2v_T2V_14B_cfg_step_distill_v2_lora_rank64_bf16.safetensors
|
|
├── text_encoders
|
|
│ └── umt5_xxl_fp8_e4m3fn_scaled.safetensors
|
|
├── vae
|
|
│ ├── wan_alpha_2.1_vae_alpha_channel.safetensors.safetensors
|
|
│ └── wan_alpha_2.1_vae_rgb_channel.safetensors.safetensors
|
|
```
|
|
|
|
3. Copy this repo or [SaveVideoRGBA.py](SaveVideoRGBA.py) into the `ComfyUI/custom_nodes` folder.
